aw, funs over, looks like their entire channel got nuked
teams of fortress 2 is some weird horrible mobile game made by some random dude. imagine the shottiest unity-lookin'-ass garbage TF2 clone, except entirely composed of TF2 Valve assets, from animations to models to sound to... everything. that's the game!
it was released on the play store sometime ago then got taken down because... well as you can see from KevinIsPwn's post, the game has cosmetics just like TF2, which you pay for...
anyways, sometime later this video (originally linked) was uploaded, with the uploader claiming the game would be returning and the description read:

evidently that wasn't the case
