the Smart Gun from Aliens as a mod for Vanilla Doom
Smart Gun From The 1986 Sequel: Aliens (This MOD Was Extracted From A MOD I Found Online & After Multiple Tries, I Was Able To Get Working Properly Thanks To The Program Slade 3)
Note: there might be some minor glitches with the sprite in certain expansions/mods, but, in most cases, you should be fine. and for the most part, it should be working perfectly. I did my best to get this weapon working on Vanilla Doom and always attempt to test them out as much as possible. I've also attempted to use the proper sound effects for this weapon that matched the gun from the film as closely as possible.
