I don't see how Tripwire can introduce mod tools and crossplay without them conflicting in KF3. Either mods are gonna be very simplistic or not available for consoles completely which kinda defeats the purpose.
Most KF2 mods were mainly one-sided. There were some weapon mods but most of them just looked bad visually and it's usually plethora of sidegrades, like pistols, AR's etc. There was a mod with Halo weapons but none of the EU servers had it, probably because it's not whitelisted either.
Custom maps, specifically ported from other games: HL2, Painkiller, Borderlands, Stalker and many more - this was the core fun for me.
I'm not sure how servers could work, will we be able to create
