I think that some game modes are more fun than Redmatch 2's, like TTT and Gun Game. However the playerbase is all but dead, so Redmatch 2 is really the only option unless you have a group of friends to play with.
Nope. Battle Royale is the only one coming to Redmatch 2. There are not enough guns for Gun Game, and the movement is too fast for TTT. I would need to create new maps as well if I wanted to add TTT.
