A new FPS game's popular co-operative mode, commonly referred to as MvM, it's a wave survival game where you defend your base against a horde of robots, while upgrading your character's stats and abilities between rounds.
Now you have the chance to turn the tables, as Operation Rewired Rampage, which runs from June 17 – August 26, puts you in the shoes of the attacking robots. The aim is to fight your way to the Red base and deposit a bomb into a hole in the front yard, much as the enemy robots do in the regular MvM mode. The event is hosted by MvM community site Potato.tf and features "over 20 missions across 14 different maps."
Operation Rewired Rampage is being held in aid of Direct Relief, an humanitarian organisation currently focused on ing victims of the war in Ukraine. So far, the charity drive has already sured its initial $10,000 goal and is currently closing in on the $12,000 mark at the time of writing.

If you want to the action, Potato.tf is running Operation Rewired Rampage servers in North America, South America, Europe, Asia, and Australia – so wherever you're located, you should hopefully be able to jump in and try the mode out for yourself. Donating to the fundraiser isn't required to play, though it's certainly encouraged if you can afford it.
As for Team Fortress 2 itself, fans have been left a little out in the cold lately, prompting Valve to take to Twitter in response to the recent two of the game's most popular mods returned to action following radio silence from Valve.
