Halo 2 was a game that, for many, was an integral part to their younger years. My friends and I had a lot of fun just playing the multiplayer and campaign, but whenever that got old, we worked on discovering secrets within the game. Now, the ability to find skulls in this game has been documented better in other sources. I've been surprised, however, to note that a detailed set of instructions on how to get out of campaign maps does not exist. As such, I've decided to set out to describe two of the most interesting places to explore when outside the maps. For the sake of simplicity I have chosen methods that do not require the "grenade jump" used in other levels to reach higher locals. (This method basically entails throwing a frag grenade at your feet and jumping right before it explodes, which gives you a boost of a few feet to reach places normally out of reach.)
The two levels that will be used in these instructions are Cairo Station and Delta Halo. Hopefully, after seeing these methods you will know what to look for in other maps to find your way outside of them.
