Halo: Campaign Evolved features two main types of collectibles that can be found throughout the missions in its campaign: Skulls and Terminals. None of these collectibles are missable, as you can always replay any mission or checkpoint to search for them. Finding them all will not only unlock several extras for your playthrough, but will also earn you numerous trophies and achievements.
There are 55 collectibles to find in total across both categories. Since most of them are very well hidden throughout the levels, you'll probably need some help if you're aiming for 100% completion. That's why we've put together this section of our guide to make your search easier and ensure you don't run into any trouble. Below, you'll find more information about these collectibles and everything you need to know.
Skulls are a classic feature of the Halo franchise and the most important collectibles in this game, as they unlock special modifiers that apply unusual, useful, challenging or simply fun effects to your playthroughs. There are 39 different Skulls scattered throughout the levels (three in each mission), as well as three additional Skulls that aren't tied to any mission. Here, we'll show you how to get them all easily!
Terminals are computer-like devices and the game's second type of collectible. They unlock codex-style entries that expand on the lore of Halo's rich universe. There are 13 hidden Terminals in total, one in each campaign mission, and this section of our guide will show you exactly where to find them.
