Crawlout New Vegas+ with working controller sprint and crouch (Steam Input layouts too), A jump / Y interact, and a crash-free F7.
A remix of Crawlout New Vegas+ by Clunt 585: the same 2-3 player co-op New Vegas, with the controller fixed.
Everything else is the original: shared fights and story, your own Courier, revives, group respawn, XP for all, your own loot, trading, compass/map markers, Titan power armor, Quantum Trigger time stop, Automatic Riot Shotgun, Performance mode, and every key in MojaveCoop.ini (new: [Keys] Crouch=LAlt).
Original mashup: Crawlout New Vegas+ by Clunt 585. Included: New Vegas Tick Fix by carxt, Tgspy, lStewieAl and WallSoGB (LGPL-2.1) and Mod Limit Fix by iranrmrf (GPL-3.0), built from their public source. Recreated ideas credited in the original: Quantum Trigger (Hopper31), Automatic Riot Shotgun (Stonedturtle26), Loot Menu for FNV (Gribbleshnibit8), Titans of the New West and Enhanced Movement (Wombat). Built on xNVSE.
