Where sniper rifle only has this choice.
One problem could be that the player could put up several sniper guys, and just wait until the aliens popup and shoot them down automatically.
Maybe this should be possible, but it should come at serious penalties. For example, I think if an alien pops up in front of you, you are more likely to
shoot him down quickly, but if he runs two metres from cover to cover some 50 metres away from you, and you were _not_ expecting this, then I think a sniper who
fires at this fast moving target is much more likely to just miss - or not even have the time to fire.
Besides, it could be a civilian too, so maybe extreme range should count for civilians that move as well and result in snipers killing civilians too, which
wont make many superiors happy ... i mean, how would you know that guy aint an alien, if he is like 100 metres away and you fire in reaction mode on
everything that moves anyway... could maybe include your own team squad too hehe
