For sure.
In General i Use murphys law, to anticipate what not should happen, and then i prepare for this worst case.
I am playing on pc since 1989, and I allways tried to push the Handicap to a maximum. The training effect is extreme high.
But for this game u need some shooter experience.
Hide in the fog, but do never give them a Chance to Enter the fog alive.
Alllways Scout with the soldiers from the lines behind. Then u have more tu for the good Placed soldiers in your Front line. Do never Use your last soldier with tu for a shot u must hit. Allways have 1 in petto for such an incident, you cant predict.
I am a Fan of goldratt, and like this "theory of constraints " i play all games. A chain is not Stronger than its weakest link. So push all ranks in the Same Speed. Even try to Split the kills fair between
All soldiers. Then you will reach low losses.
Grenades and gren.launcher are my Favorite weapons.
Try to lure aliens out of their save places while using max.hitpoints soldier out of the fog where He can only be sighted From a small angle.
When u got major+ ranks Use the Reaktion fire with heavy neddlers while crouched down with 2 or 3 soldier/camper. But do never Place such a Camper in a place, where an Incoming alien can shoot you without entering a place where He is seen From all the Campers u placed.
