Hey!
When you get the hang of making halo 3 maps it's easy! Here's what you do!
1) First go onto the Forge Lobby from the main menu or Switch Lobby option!
2) Then when your onto Forge Lobby click X and pick your game options e.g if you have infinite ammo or your invisible!
3) Once you have picked all your game options and type of game and which map it is e.g. Game: Slayer, Map: Last Resort! Just press start game and your about to start!
4) Now you're playing and if you want to edit the Map press Up on the Analog Pad and you will turn into Sparky! Then click X and you can pick what item you want and put it on "your" new map!
5) Finnaly to save your new map, press the Start button and go onto Save as new, then name your new map and you give it a description!
Soon you will be making great maps and having fun!
(P.S You can add my gamertag it's Da HaloAssassin!)
Hope I Helped
