Not going to lie, not too excited about the rocket launcher. Sure it looks cool, but it seems very similar to the Cow Mangler's charge shot. Then again, it also looks extremely fun to use, albeit inefficient.
The new pistol looks cool, but the shotgun is meh. Slow scout is dead scout, and resetting speed on jumps is bad, as the scout jumps a lot. I guess the SMG and the sniper rifle are cool, although I'm still not sure why it decapitates people/what the focus is for.
Flare gun looks cool, one of the best new weapons. Seems to be a mix between the Detonator and vanilla Flare Gun, with a built in Force-A-Nature knockback. I doubt it is going to be as big as the Force-A-Nature's knockback, however.
I predict heavy crafting in the upcoming days to try for these weapons.
Also, lack of a new flame thrower makes me sad :(
