Pros:

It's the freakin original Beta Survivors

Good quality and attention to detail

Hud icons

nuff said, don't need to explain anymore.

Cons:

Francis crashes the game......A lot, so it's really frustating

Francis's primary weapon when carried on his back is backwards (The gun is flipped and is facing the other direction)

Medpack for Francis is upside down

Melee weapon for Francis doesn't show on his back when your carrying one

Louis doesn't have boomer bile texture everytime he gets boomed on.

Why is this not made for the original l4d game?

Conclusion:

Damnit, I love the original beta survivors, I've been waiting for years for someone to finally make this. But as you can see in the cons, most of the problems link to Francis. Just get him patched up (no pun intended) and that one glitch with Louis and this will be perfect. :)
