You, the gamer that like to blast alien foes

(Note that ''Alien'' is strictly in the sense : xenomorphs)

You like to face legions of beings threatening Humankind ?

You like to face hordes of xenomorphs with a flimsy gun, a flak jacket,
and only one magazine left ?

You like to be fired upon by obescenely powerful weaponry ?

You like to command a squad of rookies under fire, trying to save them
from their own incomptence ?

You like missions that are hard, challenging, that push you to yours
limits ?

There is a game that does that better than Resistance, Halo or Gears of
War. And it's....

XCOM, Ennemy Unknown.

(the only issue is the the graphics make Doom look like a next gen
game. Doom one)
