Halo is famous for its multiplayer, and as a result of its popularity the competition for first place is stiff. One of the most important things you can do to get better at multiplayer is to memorize the maps and figure out where the best weapons, choke points, and health drops are; a quick trigger finger won't do you any good if you're getting ambushed. So for your teabagging pleasure we've compiled a list of Halo: Reach's maps with full details on where the best equipment and attack points are at.
Each map guide features a downloadable PDF of the at the top of the page, click the image to view it or right click to save. Print it out and stare at it until its image is burned into your brain, or just drag it into the bathroom if you're out of reading material. Once you've washed your hands, get out there and get some wins.
Note: The particulars in this guide such as weapon locations and suggested armor abilities are based on a game of slayer.
