1) Humans make big show with ship at attack sites. Easy to see from site, aim at ramp when it just touches down for positive effect!
The aliens all aim at the ramp with full TUs reserved on the first turn.2) Make sure no smoke or buildings block path of sight to ramp, they no make smoke so no worries on them blocking sight.
An initial smoke grenade can really do wonders. You can organize troop order in equip screen.3) Take advantage of night, they can't see in dark for strange reason, don't bring any light so to keep dark.
Flares are also good. You can even prep grenades/smokes in equip, and they stay so.4) Target lone units, easy target, no way for them see who did.
You probably already know this, but don't spread out too much, just enough.5) Beware human bombs, is weak boom but still boom.
Grenades are seriously your friend. You practically never miss with them.6) Open door first yes, no walk through, is easy, just use thingy on right when by door.
When standing by a door, right click it to open it at the cost of like, four to one TU. Very nice.7) Weapons weak, is funny. Strange lasers in laboratory however, will investigate more.
Better weapons are a must. Terrible armor, hit chest and will die. No need fancy aim.
Same with armor, really.9) Focus on enemy, they no go several ways, flank chance small.
Flanking is a great way to crash into enemies hard. Sides and backs have less armor!Is all now have, will find more. Sorry for Engluk, condolence for genes. Remember, no hit.
