Zombie/Crimson Head The same 'ole same 'ole zombies like usual.... or are they? On first encounter they sure are normal just shoot 'til they fall and blood surrounds their body, or pop their head. Be warned! If you don't burn that body or pop that head, That normal zombie will come back as a Crimson head. Which are faster stronger and all around more lethal and terrifing.

Zombie Dog These dog are more than likely the biggest pain in the series, well at least in my opinion. They are fast and usually attack in groups. When you run into one just shoot until you hear a yelp or you see blood spread around it's body. If you knock it down take advantage of it and aim down and shoot 'til it dies.

Bee The Bee's can be very tedious if they get into large groups. They really aren't worth the waste of ammo, so get what you got to get done in that room and get out if possible. Only shoot if they are causeing damage.

Spider The Spiders are relativly easy enemy's. Best thing to do is just auto-aim and fire in their direction until they drop. but be careful they can and will poison you, which is probably their most lethal feature.

Hunter Hunters are probably the most lethal enemy in the game. They are fast and strong. IF you don't have a Shotgun or another stronger weapon on you your best bet is to run. Be careful out their claws, they'll knock your head right off.

Chimera Chimera's are tricky little monsters. Try to keep away from them then turn and fire. Alone they don't pose much of a threat but with 2 or three they'll take you down before you can do anything. Chimera's will pop out of the vents in the lab so be careful.
