If you’re at all into the Halo modding scene, you'll have likely seen RejectedShotgun on YouTube. They're well known for pulling off what I can only describe as feats of incredible ingenuity, creating mods that many, myself included, thought were impossible.
Before I dive into the details, it's important to mention that this is for Halo 3 on Halo: The Master Chief Collection, and the mod is accessible via Steam Workshop and isn't available on console.
From mods featuring more than 20 vehicles and brand new weapons to Ultimate Forge, which completely reimagines Halo 3's Forge mode with massive sandbox maps, Scarabs, AI spawning, and countless new tools, RejectedShotgun has consistently pushed the limits of what Halo 3 is capable of. Today, though, I'm highlighting their latest project, Permafrost.
Permafrost, to me, feels like a nod to Halo 5's best and only real contribution to the franchise: Warzone. It was a massive objective-based mode that blended Big Team Battle with AI enemies, bosses, and a progression system that made matches feel like they evolved over time.
Thankfully, this is Halo 3, so there are no microtransactions to get in the way. Designed for up to 16 players, Permafrost focuses on large-scale objective gameplay, with each team fighting alongside AI soldiers. It also introduces what creator RejectedShotgun calls a resource economy.
Teams capture plasma batteries scattered across the map to increase their power level, unlocking progressively stronger weapons, equipment, and vehicles as the match unfolds. Players can even call in weapon drop pods and vehicles, giving battles a constant sense of escalation rather than the static sandbox Halo is traditionally known for.
Probably the biggest highlight, though, is just how dynamic every match feels. This isn't a case of loading into a map where the objectives stay the same until someone wins. Teams can capture a teleporter to gain faster access to enemy territory, destroy the opposing team's spire with a MAC strike, and permanently change the battlefield in the process.
Once a spire falls, defenses disappear, objectives move, and the battle shifts into an entirely new phase. Throw in massive vehicles like the Mega Mantis and Pelican, AI battling across the map, and enough explosions to make Michael Bay blush, and it's honestly hard to believe this is all running inside Halo 3.
Now, I love Halo 3. It's my favorite game in the franchise, and I just wanted to highlight what I think is a pretty impressive mod.
