Hint: Cr0wned Achievement - 01/13/09

To kill a witch with a headshot, put the game on Easy difficulty, acquire an auto-shotgun, and look for a witch. The player going after this achievement should simply (and quickly) approach the witch (lights off), causing her to rise. As the witch is standing (she is slower to attack on easy), unload all 10 shells into her head.

Hint: Fire. And Lots Of It. - 01/13/09

The infected cannot extinguish fires once they are ignited (all modes - but especially in versus mode). Use that to your advantage in the campaign by using the molotov (or igniting gas cans) on tough targets like Tanks and Witches.

Hint: Hot Swap - 01/13/09

If you need to 'reset' your primary weapon to its original (cherry) state, pick up a weapon different from yours, then re-select the weapon you want. This is faster than reloading (plus the time used from replenishing from the ammunition pile), and can help in close-call rescue finales.

Hint: Quick Reloading - 01/13/09

If you're around enemies and need to desperately (and quickly) reload your weapons (primarily of the machinegun or pistol variety), try the following. Hit the reload button and then immediately hit the shove button to push a nearby enemy. When your gun(s) return to shooting position, they are automatically reloaded without having to wait for the clip to go in. This will save you precious seconds, and can even save your character's life if you find yourself in a bind!

Hint: Reloaded Defence - 01/13/09

When reloading any weapon, your survivor can keep attacking with the melee button. The reloading sequence will continue unabated.

Hint: Speed Life - 01/13/09

As the director's commentary points out, the Tank can be outrun by any survivor with green (51% or more) health, but the Tank can overtake any survivor with 50% of less life, because the more injured a survivor is, the slower s/he moves. Pain pills will boost the speed of an injured survivor, although the color of the life bar will reflect his/her original health status.

Hint: Unbreakable / Stand Tall Achievements - 01/13/09

Do these two achievements on Easy difficulty (duh!) and get into the habit of running back to let other players (or bots, if on single player) take out the Tanks and enemies. On single-player mode, if a bot accidentally heals you, you can die, restart the map, and not have that count against your achievement. However, if you are playing online, that exploit will not work.
