do you guys know the name of this mod?

i remeber when i was a kid i played a half life 1 mod, where every weapon is empowered, and you can change their mod using f, i remember there was a nuke with the rocket launcher, but consumes all your ammo, the little monsters you throw u can summon the giant big one and the laser i dont remember but i remember some type of weird projectiles that it shoots and it bounce i think? does this mod seem familiar to any of you? if so please let me know i really miss that one mod and thank you :D
