Left 4 Dead 2's Versus mode getting bots

Valve announced on its blog that it’s currently finishing off a couple of updates for Left 4 Dead 2. The changes will be available in the coming weeks for both PC and Xbox versions of the game, and affect the Versus mode.

The changes are

Bots
We are adding bots for the Infected team to help out the Infected when they are down a man or two. This will also make 1v1 Versus a bit more fun.

Auto-spawning
We’ve also been experimenting with a solution for auto-spawning in Versus finales. Even though it’s pretty obvious from the L4D forums that EVERYONE LOVES auto-spawning in finales, we figured, what the hell-we’d just go ahead and remove auto-spawning anyway. But before we make any change to Versus we always need to see how the game is currently being played.

So how do finales currently play out? Across all finales in Left 4 Dead 2 currently, a single survivor has a 34.56% chance of escaping. That includes the Concert Finale in “Dark Carnival”, which boasts close to a 50% escape rate (and yes, a fix for everyone’s favorite cheese spot is coming). Remove the Concert Finale, and we see the average drop to 29.61%. With these figures in mind, when we make changes, we can measure the difference and see how much the change impacted the balance.
