not sure how much this will be updated with new stuff but here goes regardless

-arms for the Thompson and Flamer (that can be optionally turned on/off) (introduced in a recent update for Serious Sam Classics Revolution)
-the ability to choose between different HUDs from a dropdown menu (like classic TFE, blue TFE (iirc called Warped in Rev), Classic TSE, Modern, etc.)
-the Plasma Thrower and Minelayer that were introduced in Rev (alongside ammo pickups and what not)
-ability to customise the contents of backpacks, like removing cannonballs or flamer fuel for example (if even possible without making it too complicated)

edit: -usable serious bombs similar to how it was done in the xbox version and different powerup pickups

thank you for making this SWEP mod
