Hints

Do not let the Bomber come close. Shoot him from a distance. Otherwise he will explode and deal a lot of damage.
Kill Piper as soon as possible or he will call siblings to his aid. Piper will fight back aggressively when cornered.
Move fast when Thrower begins to launch his projectiles. Be sure to attack him when he is trying to fall back and reload.
SH Security: Former security officers' armor makes them tough. These guys are hard to kill.
Zombie scientists cannot be stunned and will advance until they are killed.
Reload whenever possible. Top off all weapons before heading into a fight.
Avoid refilling your weapons after firing just a couple of bullets. You'll quickly run out of it.
Always be On the lookout for Bonus Crates.
Try as much as possible to choose the best weapons for missions.
