I have no clue how difficult it's to create plugins but here's my requests:
Every enemy from TR1-TR5
I know there's tons of enemies out there to be downloaded, but most of then don't behave like they did in the original games, i'm talking mainly about the most unique enemies. It would be nice to have proper slots for the T-Rex, the Torso, Bacon Lara, Natla, the Dragon, Tony, Sophia, the TR3 mutants... Anything that can't be properly made with TR4 slots.
Every weapon from TR1-TR5
It's still not possible to have fully working magnums...
Dual aim
Just a small little thing that i think would be really nice to have.
