Monday Night Combat

Can be done easily on Xbox Live with teammates or by yourself. There are twenty waves of enemies that attack at a moderate level, and you have to stop them getting to the money ball.

Tips:
+ Always upgrade your class before adding turrets, while both can die only you can regenerate. So you won't lose skills.
+ More turrets are usually better than a lesser amount of upgraded ones.
+ When the Mascot appears, forget about everything, concentrate on draining money out of him. Once he's finished use the money to upgrade yourself and turrets.
+ You can buy a full stack of juice for $500. Very useful as a last resort.
+ Only save money for one thing at a time. Losing the game while having thousands of dollars left to use is not something you want to be bragging about.
+ The ejectors are cheap and easy ways of clearing an area.
+ There should always be at least one support to hack turrets, heal, and generally fend of enemies. More than two supports are not a good idea as if they are overwhelmed, they are screwed.
+ The assassin is the least favourable class for this as they can't get rid of many enemies at once and are light and have low health, but they can help in getting rid of a few enemies.
+ The Jackbots can be a nightmare. Coordinate on getting rid of them one at a time and try to avoid his ground pound by jumping, hovering, staying above ground.
