The Halo Processer never appears in game but is a forerunner mix between a guilty spark and a sentinel.It can repair units and attack Enemy's with a high damage and high fire rate at the same time. It's weapon is a beam cannon that has infinite ammo but needs to recharge. It is seen in battle by many Marines but none live to tell others. Except for a few that got lucky when covenant distracted it. It has blue glowing eyes with a white half circle shaped head. The body is a big bulky white triangle with the main beam cannon on it. The front legs are long and have sharp forerunner sword like matter on it protecting the joints. the back legs are shorter when anchored but it is like a frogs back leg it folds up but when needed it launches the processer into an airborne state and can attack air vehicles. The last part of the processer is a tail with a blue glowing sword like mass that act like on of a scorpion, it injects poison into the victim killing them in less than ten seconds. It is also like an emp because when put near vehicles (except for forerunner tech) it brings them to a stop and all weapons that are powered by electricity are shut down.
