The graphics were...there, but they were still okay. It reminded me of Halo very slightly, so I gave you a high style rating. I was playing while my parents were in bed, so I couldn't play with sound, so I gave you average, assuming that they were decent. The violence was good, as was the interactivity. I didn't see any room for humor. A few tips, though. Make the gun range a bit longer, because the alien guns can go right across the screen, but your gun only goes about a third of the way. Maybe make him able to shoot while crawling. When fighting the aliens with the turrets, I found myself getting impatient with just shooting them, so I had to use a grenade. Can the turrets actually be destroyed with bullets, or are they invincible against everything but grenades?
