Having a tough time designing Halo: Reach Invasion variants in the game's expanded Forge utility? Yeah, us too -- that is, until we read Bungie's handy little guide for budding modders, which breaks down the process of creating an Invasion map from start to finish.

The guide provides the know-how for setting up CTF and Assault-based objectives (and a host of other options), in addition to the 4-1-1 on creating multiple objectives in each phase of your custom Invasion game. If knowledge is power, then this guide is the equivalent of hooking up your brain to a car battery.
