Remember Brink? I initially looked forward to that game because it promised me a parkour competitive shooter, and that idea seemed awesome.
Alas, that wasn't what the game gave me. Not a good one, anyway. This Mirror's Edge inspired server mod for TF2, though? Looks like it might just pull it off.
The developer, explaining how the mod works:
While in Parkour Fortress, speed, timing, and precision are used to the player's advantage (or in some cases, disadvantage) to pull off stunts and tricks while keeping momentum, and either reach the end of the course or to bring all of the flags to one location, thus winning the round.
It's perfect because, any time I play as the scout, I'm mostly doing it for the thrill. His pace and speed are really something else. And this mod looks like it takes advantage of that.
