These are some things I really want to see fixed/implemented in the final BM Steam version, Just my opinion
- Xen (Which is obviously gonna be included)
- A fixed Crowbar animation, like the HL2 one or better(this one has a very poor feedback IMHO)
- Big Picture Mode Support, such as HL2, portal, TF2 in the new update.
- Mac and Linux Support
- Maybe an interface more fancy, like the Portal 2 or Left 4 dead one
Correct me if im wrong with something, im not very much into the source engine development.
