The Graphics are Excellent. I swear it uses the Half-Life Engine, or Blue shift uses its engine. It looks SO Similiar to Half-Life, maybe a BIT better. The explosions and weapon affects are well-done. The fleares are blinding in the light, flickering lights, and fans turning off have teh right movements.
Characters look real.
Except for the grenade fire. You can tell the creaters liked and were fascinated by shrieks and beeps. The Aliens in the middle of dark hallways While playing the marine is truly freeky sounding and made me jump out of my seat a few times. The option of playing through the game as each of the three species is great. It ups the replay value of the game a notch or two.
