Title: Attack which UFO with what ?
Post by: anonymissimus on November 17, 2015, 03:16:10 pm
As I never do saveload - also not when in the campaign environment - I would like to hear some experience.

Is there a way to take down a harvester with only human tech for instance. Generally, I attack anything larger than a fighter only late in the campaign when I have starchaser already, which can take it down safely (with 2 particle beams, 1 laser and 2 alien warefare suits, no armor). Recently I downed a fighter with a saracen (2 particle beams, 1 alien warefare suit, 1 targeting computer, no armor) and survived with 4% hitpoints or so. When I already was that low I decided that only killing the fighter would safe me now, as I would probably have been hit again while trying to flee, and it worked. So this was too risky, I can't afford losing the 50000 credits or so which this ship is worth. This was in 2.6, where saracen has less hitpoints than in 2.5. IIRC a fighter can be taken down by a stilletto with 3 lasers too, don't recall about the electronics but at least 1 alien warefare suite seems mandatory, and no amor. As armor makes the ships slower, I often don't use it.
Human techs only are insufficient to attack anything armed as to my knowledge, so only scouts and supply ships are possible with those, which makes the human tech air rockets useless.
EDIT
IIRC I also once, in despair, destroyed a harvester which was chasing my firebird dropship with all the good soldiers on board using 2 stilettos and a ground SAM site. The stilettos were IIRC armed with 3 lasers each and no armor, don't know about the electronics. The harvester ignored the stilettos and continued chasing the fleeing firebird, which made victory possible. As stilettos are slower than harvesters, which appear very soon, I normally prefer saracens instead, as stilettos cannot flee from a harvester chasing them.

you can take out every UFO (important: which has NO rockets equipped!!) by using 2 Stiletto-fighters with sparrowhawk AA missiles and some armor.

With the missiles you can fire while the cannons of the UFOs are still not in range:

- for best results launch both Stilettos from the same base at the same time
- approach the UFO until the first missiles are fired
- immediately do a 180° turn to fly away from the UFO
- when the missiles hit the target do a 180° again and fire the 2nd salvo of missiles
- repeat

It's a lot of micromanagement which is best done with no time-compression set. Of course the UFOs are faster than the Stilettos and will come in weapons range at some point. But usually they will be shot down before.

I'm sure some will say this may be cheating or misusing game mechanics. But I feel it's a legit tactic to do so.
If you know you can fire at the enemy before he can fire on you, you always try to stay out of his range while pounding him with all you've got. What's good enough for warships on the oceans is surely good enough for well experienced fighter-pilots in their struggle against an superior enemy.

If you found the foes weakness - use it.

Ah.. by the way... I didn't test this on hard or very hard. So maybe this tactic won't work there.

Thanks, nice. Well, when fighting melee enemies in ground combat (kerrbladers, spiders) we're doing basically the same, right ? I don't think air combat is affected by difficulty.

Fighters and harvesters then, but not corrupters, gunboats and bombers. (And of course the unarmed scouts and supply ships.) Fighters are slower than stilettos, so the tactic can be used safely against these.

I am using this tactic too. The aliens are basically asking for it if they let themselves be outranged by the silly human sparrowhawk.

However, it feels wrong that this can be used to win all fights vs fighters and harvesters unscathed.

Three easy solutions come to mind:

Three easy solutions come to mind:
  • Limit the ammo of the sparrowhawk, so that hit & run is possible but cannot be abused indefinitely
  • Increase the speed of ufos while they are in combat so that they can close in
  • Give Ufos some long range weaponry so that they can shoot back [\li]


I think there's no need for a change. Keeping 2 Stilettos in the base(es) is expensive. In both money and space (hangar, equip). You can't keep doing this for ever. Especially in mid-/endgame when Stilettos are almost 1shots for the bigger UFOs.

Not sure whether I would want to do it too. Following harvesters with saracens to catch the mission when they land yields an undamaged UFO and thus a good deal more money, with less risk and costs.

I think there is.

Before I knew of this exploit, I already regarded the sparrowhawk as the best early game aircraft weapon, overshadowing the TR20,
I kept two stilettos in each base to be safe from fighters. If one was damaged in a fight, the other one was still available.
I also rushed the research of aerial laser and particle beams to make my airfleet more reliable.
Attacking harvesters was impossible before having access to the dragon.

With the exploit, it is completely safe to use only one stiletto to be safe from fighters
And there is no reason anymore to research aerial lasers or particle beams, or to even equip an ECM or targeting computer.
Harvesters are a piece of cake with two stilettos and completely safe to attack.

This disparity was clearly not intended by the devs.
Not sure whether I would want to do it too. Following harvesters with saracens to catch the mission when they land yields an undamaged UFO and thus a good deal more money, with less risk and costs.

I agree that it is most often preferable to let harvesters land.
However, it saved my butt once to be able to shoot down a harvester heading for one of my bases.
Also saved my butt once,

A harvester might show up and target your stiletto when it's far away from a base to escape to so you're f*cked. The risk balances the exploit.

The money for the hangars sure is a big deal as well, I'd rather have more labs instead.

Sparrowhawks are heavyweight, saracens or the nose of a starchaser cannot be equipped with them. And missiles are kind of expensive, I don't want to pay that for shooting supply ships into the sea.
EDIT
And without hoiba's exploit, what usage would the human aircraft weaponry have ? I found them to be useless otherwise (against armed UFOs).

That can happen but harvesters are only slightly faster than stilettos.
Worst case you loose the stiletto and insta-buy a new one for 20k(stiletto) + 2*7k(sparrowhawk racks). 
Still cheaper than a hangar and you save the maintenance too.

Granted, the aerial laser is kinda neat to shoot down scouts and supply ships for free.
But the point is that there is no pressure to get it.

By the way, is the saracen any good? I never tried it out.

EDIT

Their use is to enable shooting down fighters.
The exploit trivializes that, making the sparrowhawk the best weapon (better than particle beam, it is better than TR20 anyway) until you get access to advanced aircraft.

I think the exploit is actually fun, introducing some tactics and micromanagement into air battles.
Still it is an exploit as fighters are completely helpless against it.
I would prefer long range weapons to be a strategy and not an exploit, by somehow enabling fighters/harvesters to fight back.

Well, it's not an exploit in my opinion. This tactic would be used by every real life fighter pilot as well. If he knows his weaponry can out-range the enemies he would use hit-and-run as well.
Dogfights, where the planes are circling around each other at short range almost never happen since WW2. It's all about long range rocket hits and stuff.

Different weapons have different ranges/accuracy. You also use snipers at long rage and AR at short/med range, aren't you?

And it perfectly fits into the story: aliens learn that their particle beams are not effective against sparrowhawks and come up with the alien rocket tech.

It's only an exploit if you pause the game to do the micromanagement.

I completely agree that outranging the enemy is a valid tactic and I like that there is a weapon available to do this.
However, a real life pilot would not have unlimited missiles to play with.
And he could not hope to outspeed an ufo with antimatter drives (by the fluff).

oh .. I didn't know there are unlimited missiles... that should be fixed.. I totally agree.

At least I never ran out of them and the description of the sparrowhawk does not state any ammo.
I ran out of shiva / aerial laser ammo though, and these state an amount of ammo.

So I guess once you equip a sparrowhawk, you have unlimited missiles for one interception.
I would suggest a limitation of 2-3 missiles per rack, so that one can kite certain ufos, but not forever.

Well.. if we take the actual F22 Raptor as basis.... it can equip 6 med-range AA Missiles (AIM-120) ...so 3 sparrowhawk per stack would be perfectly fine.

I just try to lure through SAM sites any UFO that acts aggressively (turns to intercept). If it somehow survives, turn and attack it - preferably on the far edge of the last AA circle, so it could squeeze a few more shots.
Title: Re: Attack which UFO with what ?
Post by: Pharaufein on November 24, 2015, 12:38:14 pm
Luring through SAM sites seems like a decent strategy, but I guess you need at least one on every continent to be able to do so.
I never build any SAM sites because the number of installations is too limited.
Building radar towers to get better coverage is much more important imo.

Of course more bases allow for more installations, but building and maintaining them is way too expensive.
And if you have them, you can as well use them to host more interceptions which are much more versatile, instead of building more SAM sites.

By the way, why are there not laser sites as soon as the laser defense turret is researched?

EDIT: And why is the number of installations limited? I assume it is to prevent too cheap radar coverage?
But then it would be sufficient to limit the number of radar towers.

1 in North America and 1 in Europe are sufficient. A third one in East Asia perhaps. And you need an interceptor there as well for luring, and be prepared for attacks onto such bases. You can take down gunboats safely as well, which is important, since they will destroy the dropships otherwise.

It safes a field in the base which the base-hosted rockets would consume though. (I build them onto the same spots as the main bases.)

I just checked the aircraftmanagement.ufo file states 7 as ammo for the sparrowhawk.
This is of course more than ever needed to down a fighter, so I never noticed the ammo limitation.
 
I tested setting the ammo to 3 and downing a fighter with a single stiletto suddenly was not guaranteed at all anymore.
If some missiles miss, the fighter might well survive the three salvos.

I tried using this 2 stilettos with sparrowhawks (greater range than particle beam weapon) vs harvester exploit, but my impression is it is too dangerous and costly. It's also often not possible to reach a harvester flying by in time. 3 hangars are too expensive, strategies with only 1 stiletto + SAM site are too dangerous too. So I recommend to use the exploit only against fighters and use a second interceptor hangar for a saracen which can safely follow harvesters to see where they land, and potentially lure them safely to ground defenses.

Post by: Pharaufein on March 29, 2016, 02:57:03 pm
I like the idea to have a saracen follow a harvester to not let it slip through the radars. But don't harvesters turn around to kill the saracen?
Title: Re: Attack which UFO with what ?
Post by: anonymissimus on March 29, 2016, 03:35:46 pm
Sometimes they do. But saracens are faster than harvesters, so always can run away. When the distance to the harvester has become large enough, they give up (as for any UFO chasing a faster ship). By repeatedly holding position and moving, the harvester can be lured into ground defenses range.
Re on the sparrowhawk  exploit. I think a similar technique should be usable on starchaser vs gunboat. A gunboat has 3 particle beams in addition to 2 alien launchers. A starchaser can only be equipped with the 2 launchers, but she's faster than gunboats and by staying out of range of the particle beams, the weaponry can be made equal. Hitpoints and electronics are superior, so a won fight.

Post by: Zverko on July 12, 2016, 07:29:31 pm
My two cents: I was able to take down Bombers and Gunboats with basic Starchaser luring them over the laser-defended base. The trick was to attack and, as soon as UFO makes a visible turn to fighter, land it. Usually the alien rockets just disappear (since the target is in the hangar), and starchaser's missiles hit the target. UFO also flies in the direction of the attack for a while, staying in the zone for lasers. Then as it starts on away-from-base course, attack it again. With proper micromanagement I think even single saracen with no weapons of note can down any ufo that way.

While that tactic allowed me to win, I think it should be fixed in the code. I would humbly suggest something like behaviour trigger for UFO: if hit points are below 50 percent - stop behaving aggressively and/or stay away from known bases/SAM sites.

There was no way to take down anything stronger than a fighter for the longest part of the campaign then. I get the starchaser and thereby the ability to take on corrupters and gunboats without escaping into a base in about November or December. With gunboats cruising around uncalculatably missions cannot be flown to.

The long term goal is to completely overhaul the flight and interception systems, with things like aircraft (including UFOs) flying in formations and a more elaborate intercept system, with different aircraft behaviour (aggressiveness level, preferred range, disengaging, etc), which of course you can control in the case of your own interceptors...

Of course that needs someone to implement it first (any volunteers? :D ), meanwhile enjoy your tactics, tricks, exploits, cheats or whatever you want to call them.
