Finding the Grunt Birthday Party in Halo Campaign Evolved

In the vast, sprawling universe of Halo, every player dreams of hunting for that elusive piece of loot. And while the main campaign delivers epic action, the real treasure often hides in the bonus missions—the hidden secrets waiting to be uncovered. One such prize is the celebrated Grunt Birthday Party skull, a collectible that adds another layer of history to the experience of Halo: Campaign Evolved.

Finding this iconic skull isn’t about following a simple quest marker; it’s an adventure in itself. To track down this grinning relic, you need to dive into the final bonus mission, Heavy Burden, as the prize is tucked away not on the main campaign path, but within these special added challenges.

The journey begins after acquiring crucial information from the bridge in the second section, ‘Two-Fisted Cyborg Justice’. Once you have secured that intel, head to Rally Point Bravo. From there, follow the navigation markers down the lift and continue along the route until you ascend another short lift. This series of movements guides you through a hidden corridor, leading you toward a specific location.

At this point, you will find yourself in a large room punctuated by a load of purple torches to your left. Enter this chamber on the upper level and descend the short stairs ahead. Look carefully to your left, and there it is: the Grunt Birthday Party skull resting on top of a tall rock sculpture in the center of the room.

Reaching the prize requires a little acrobatic finesse. To get into position, head over to the central raised platform visible to your left—you can reach this by dropping down or utilizing the nearby walkway. From there, hop onto the torch resting on its edge and sprint jump over to the lower level of the rock sculpture. A final leap up will grant you access to the skull.

Once you have successfully grabbed the Grunt Birthday Party skull, you’ve completed the physical hunt. To ensure this iconic collectible stays active for all future missions, simply choose the ‘new game’ option or any other mission, and toggle the item on within the skull menu before loading in. This trick ensures that your newly discovered trophy remains active for every campaign adventure that follows.
