this game was absolutly amazing!
it has a great story line as a scientist working inside of a underground facility in new mexico when all of a sudden a accident happens and aliens are teleported to earth and you find your self fighting aliens, marines, and even zombies!
i acculy got scared from climing into dark air vents where head crabs lurk waiting to surprise you!
The excitement never stops in this combat puzzle game!
you can even go online and play deathmatches with people online using the same weapons you used in the game!
thats not all, check out the awesome mods that they have for this game like: the specialist or Earths Special forces!
