This is a complete rework of Left 4 Bots (v1). It has pretty much the same functionalities of the V1 but they have been improved, plus some new functionalities have been added.

Please note: the goal of Left 4 Bots has always been to make the survivor bots more human-like, not to turn them into super zombie killing machines.

The addon gives them some functions that the vanilla AI was missing, like defib dead players, scavenge gascans, deadstop special intefected etc, so their combat skills are also improved but they can also fail and fu** things up, sometimes. But isn't this part of the human behavior? :D

What changed?

Almost everything. The bots are more active while executing the orders, they can attack and shove infected and scavenge items. The lead order has been completely reworked and it will work on most maps, including finales. Now you can order each bot to follow another survivor or to go and hold a certain position. Bots have weapon preferences you can change. Bots can complete all the official campaigns on their own, look HERE (in The Last Stand campaign you also need this: NavFixes). And more. The commands changed too. Look HERE and HERE.

For more details, please check the videos i made about L4B2 on my Youtube Channel.

What didn't change?

The fact that L4B doesn't replace the vanilla AI, it simply adds some features to it. L4B can make the bots execute your commands, throw nades, defib dead players and do some other stuff that the vanilla AI can't do (not always successfully though) but for most of the time it's still the vanilla AI controlling the bots, with all its known defects.
