Mission Reflex

Spartan 445, Reven Frost (codename Spartan Shadow) is sent on a mission to neutralize a Covenant cruiser on it's way to Glass the planet of Haven. Spartan Shadow valiantly sacrifices himself by causing the demolition of the forerunner artifact used to glass the planets which have killed millions within their genocidal campaign. However this burns a hole through slipspace, sending Spartan Shadow to the World of Remnant. Now Reven must return to his universe to continue his campaign against the Covenant.

Were it so easy.
