Mann vs Machine
Mann vs. Machine is a co-op game mode released in the update of the same name. In Mann vs. Machine, a team up to six players attempts to prevent a horde of AI-controlled robots from carrying a bomb to their base. Players can purchase upgrades for their weapons using in-game currency, called credits. All purchased upgrades will last for the duration of the game. If a player leaves during the game for any reason, providing they reconnect, their upgrades will be retained as well as their credits spent and remaining.
The only achievements obtainable in Mann vs. Machine are the Mann vs. Machievements.
Mann vs. Machine uses a separate set of "Best Moments" and thus keeps track of a separate performance report. These will appear after the usual set of "Best Moments" as a client connects to a server.
The game mode currently has five difficulties: Normal, Intermediate, Advanced, Expert, and Nightmare. Contrary to popular belief, Nightmare difficulty is actually easier than Expert difficulty and, oftentimes, Advanced difficulty.
Years later after Redmond and Blutarch decide to have a truce but suddenly Gray Mann suddenly introduces himself to the brothers and murders them. Using his robots to attack Mann co., Saxton Hale hires the surviving members of red team and blue team. Blue Medic, Demoman, Soldier, Sniper and Scout survive and everyone except Scout his hired due to his injuries. On red team Engineer, Medic (hired by Gray Mann), Scout, Heavy, Soldier and Pyro!
Some tips and trick are:
1. Try to only have one person or maybe 2 play a single class. This provides a range of stratedgy that is is probably more effective then 3 scouts and 3 demo men. Everyone feels unique and everyone has their own role.
2. TEAMWORK. Team work is importasnt and the only players that should be alone are scout and/or
maybe soldier.
3. Listen to people, if people tell you to change your class be a good guy, change your class to be more helpful to the team. Plus people can easily get voted/kicked off since their is only 6 players.
