When 343 released halo 5 it was a step in the right direction. Halo 5 limited the sprint capability, had a non-skippable death timer and no custom classes. They also added some new features that were well received. Halo 5 opted to start player with a pistol instead of a battlerifle or DMR. Everyone in Halo 5 must now earn a battlerifle. The pistol is 5 shots to kill while the battlerifle is 4 shots so even a small advantage like that must be earned. But players can still sprint, climb, hover and pound so things weren’t all good.
Skulls in Halo are gameplay modifiers that were first introduced as Easter Eggs in Halo 2 to provide an extra layer of depth to the game, and to provide more of a challenge for players by altering the way the game plays. To activate a Skull, the player must first find it, which is usually a challenge in itself, as the Skulls are scattered throughout the campaign levels, usually well off the beaten path, with some requiring complex exploits, codes, platforming, glitches or even surviving a gauntlet to actually reach them.
