The new Left 4 Dead 2 demo was sweet! although theres like only one campaign and 2 levels....and they had a good improvement on the game and new zombies new weapons new characters...its pretty sweet! The best of all when u get to use melee weapons like a machatte , frying pan , riot stick ..and many more you can think of...I'm just gonna spoil the few new infected

The charger
This is a zombie that actually undergo mutation into a tank...well hes halfways...but hes much more agile and he cannot be shoved away due to its size...he will charge straight onto you and grab you and violently pounding you to death...but its health is much of a problem and basicly I dodged his attacks and killed him with a frying pan

The spitter
Well its basicly a WHORE that got horribly mutated till her tits are all saggy and this BITCH could be quite anoying...she spits out acide from her mouth and the acid could even incapitate a survivor who stands there for like 10 seconds ( I tested it out ) but the damage varies from difficulty..

The Jockey
This guy is somewhat of a hunter + smoker..he could jump on you and drag you away from your teamates and he could even drag you to witches , spitter goo , near a boomer and into big hordes and this guy's health is kinda big so you should try killing him at long range cos a headshot from a shotgun dosn't kill him

Anyways 17 of november this game is officially out...I WILL BUY IT!! I hope got korean zombies LA!!
