Team Fortress 2 today released it’s latest game mode: Mann vs. Machine. Valve’s most popular free-to-play game got even better with this latest edition. Basically, Mann vs. Machine is a co-op mode. From the official Team Fortress 2 website:
Mann vs. Machine is a new co-operative game for Team Fortress 2 that lets you and five friends wage a desperate battle to stop a lethal horde of robots from deploying a bomb in one of Mann Co.’s many strongholds. Take advantage of breaks between waves to upgrade your abilities and weapons. Survive all the waves in any of a variety of missions to earn incredible loot.
If you’re looking for a challenge, however, and are willing to shell out $0.99, you can buy a “Tour of Duty” ticket in the in-game store (Mann Co. Store) and play “Mann up Mode,” which is a bunch of Mann vs. Machine machines across various maps. This is the only way to earn the “incredible loot” (i.e. moar cosmetic items like hats).
