Teamwork

Perhaps the most important aspect of competitive Halo, and especially Halo 3, is teamwork. Compared to the first two Halos, Halo 3's multiplayer in MLG tends to focus on how every player works together rather than individual skill. Here I will give you some tips on how to be a better team player and win more because of it.

The two main aspects of teamwork are communication and coordinating strategies. Both of these are huge and have many contributing factors involved.

Communication
The most important factor of working with your team is calling out where the enemy is at all times so you can team shot them effectively. In order to do this, you must already know every map and what each location is called. For all the detailed callout names, read my call out post. Also, you need to call out the status of the enemy, including their health(ex:One Shot) and their movement(ex:He's going to Snipe). You also need to make sure your teamates know your health and position(ex:I'm weak, getting double teamed). Another important part of communicating is saying where the other team will likely spawn, depending on where the other team has recently died, or where your team is. However, calling out locations is only half of communication. You also need to call out general strategies that your team is in position to make. This leads to the strategy aspect of Halo.

Strategy
To form any strategy you first need to have a deep understanding of the game and what works and doesn't. Then you need to work with your teamates to coordinate breakout rushes, setups, and rushes. Breakout rushes should be understood by each teamate prior to the beginning of the game, and focus on getting the power weapons and powerups quickly and efficiently, gaining control of the map. For setups, the purpose is to get in a position where you can team shot and trap your enemy, making them feed you kills. This is especially evident on Guardian, where a Snipe Tower/Jungle setup will rack up kills for a long time. Rushes are especially important in Halo in order to get a power weapon or simply get a rally of kills by catching the other team off-guard and killing them off spawn. For example, when the Overshield is about to spawn on the Pit, you should tell that to your teamates and make your way to its location and try to secure it. However, you should never rush by yourself, and instead position yourself close to your teamates so you can team shot together. Rushing as a team is especially important in objective gametypes, where a group rush towards the flag, ball, or king can result in an easy capture or points.
