Why didn't I learn about Steam Workshop for Halo MCC earlier? I always did like these kind of game modes. Anyway, this is a modded campaign map called "Ultimate Firefight Sandtrap 6.0 ALPHA 5" by Weaver900 for Halo 3 (not ODST). It's a wave-based campaign map with many modded weapons, vehicles, and enemies, most from other Halo games. It's fully compatible with Multiplayer for those interested in trying it out with a group. As it's a campaign map, you can save and return to it at a different time if you wish. =================== Follow me where I am! =================== YouTube - / tehnecr0 Twitter - / tehnecr0 Steam - https://steamcommunity.com/id/TehNecr0 I do not own anything shown in the video aside from gameplay.
