No, there will be 0 new weapons and 0 new maps and even 0 updates. Tripwire took their money to Bahamas so they can live large on our stupidity...
Absolutely, mate ! Tripwire is the kind of company that supports its games many years into the future. Killing Floor 1 was updated up until the release of KF2, so about 6 years !
That i know of
What i was trying to say is, does Early Acess gets updates up until the game release? i know how damn good these guys are at supporting their games, just don't really know how EAs works
