Halo: Campaign Evolved's final mission sees Master Chief finally return to the Pillar of Autumn for a full-circle moment, facing off against an onslaught of Flood and Covenant enemies in a race to escape the ship before it self-destructs. As every other level, The Maw includes three collectible Skulls: Stowed Reload, Boom, and Thunderstorm. If you've been hunting for all the Skulls in Halo: Campaign Evolved so far, the final three are actually quite easy to grab, and assuming you've completed all Bonus Missions and collected all Terminals and Skulls on each level, you'll finally unlock the Headhunter and Collector’s Addition trophies, as well as the No Rush trophy. All The Maw Skull Locations The Maw is pretty straightforward when it comes to collecting Skulls, and players will be able to breathe a sigh of relief as all three can be claimed easily during the main progression of the mission. The Stowed Reload Skull is found once you reach the Cryo Room and is located on a pedastal in the far left corner of the room, which is lit up by some nearby flames and is pretty hard to miss. The Boom Skull is also found while completing the main objectives of the mission, but is a little tucked away in the Engine Room. Once you reach the top level of the Engine Room, you'll see a console that needs to be activated with a room directly behind it. Go near the console and drop down just to the left on the little platform, then crouch down. The Skull is in the shadows on that ledge, but you need to stay crouched or you'll end up dropping all the way to the floor again. The Acrophobia Skull will make finding the Boom Skull really easy, seeing as you can just simply fly back up to the top level again if you fall. Skull Rally Point Difficulty Location Effect Image Stowed Reload Bravo Any In the Cryo Room, in the far left corner that's lit by fire. Holstered weapons continue reloading. Boom Bravo Any In the Engine Room on the top level, on a hidden ledge to the left of one of the consoles required for the mission objectives. You'll need to crouch down once on the ledge. Explosion radius is doubled. Thunderstorm Charlie Any Once in the Warthog, follow the tunnel until you see the third cut-through on your right. Halfway along the shortcut is the Skull. Most enemies spawn at higher ranks. The final Skull, Thunderstorm, is found during the timed Warthog escape near the finale of the game. When you reach the tunnel area, count the hallways to your right until you reach the third cut-through. Go down this hallway about halfway through, exit the Warthog, and the skull will be there on your right. All The Maw Skull Effects For Skull effects on The Maw, the Boom Skull is a lot of fun and will double the explosion radius of all your weapons and grenades, but also enemy weapons and grenades as well. Be careful with this one as you're much more likely to accidentally blow yourself up, and it's also required to unlock the LASO difficulty. Stowed Reload is a handy one if you're looking for an advantage, as it allows your holstered weapons to continue reloading if you switch, while Thunderstorm will cause enemies to spawn at higher ranks and be much more formidable. Thunderstorm is also required to unlock LASO in Halo: Campaign Evolved, and is likely one of the last you'll need to unlock LASO if you've already completed the Bonus Missions and collected all Skulls up to this point.
