I saw this game a while back when my dad played it a lot and got to try it but i got my ♥♥♥ rekt too hard. It's hard to find players for it these days, but when you do it gets pretty fun. It takes a bit to get used to the game, especially if you're coming down from Team Fortress 2 to try this out. Conc jumping is one of the coolest things about this game among other stuff.

Find a group for it on Steam like the TFC Revivers or something and jump in. As the son of a TFC player who is part of the TF2 generation, I can say we (The 2 gen) should respect TFC for what it is even if you don't personally enjoy the game.
