Jaime Griesemer was hired in mid-1998 at which point the Halo team was 8-9 people mostly working on the game engine.

These RTS versions of the game had no story and were purely designed for multiplayer, though by late 1998/ early 1999, the game had fully morphed into a third person shooter. The initial revisions of what would become the Master Chief at this time were simple ~400-polygon models nicknamed something along the lines of the "future soldier", designed to be a supersoldier much like the final Master Chief, but deployable en-masse on the battlefield. The fun of using the Warthog vehicle led to the camera getting closer and closer. The initial RTS prototype was built with an isometric camera view, though experimentation with certain features allowed a third-person camera to be attached to units for control including the soon-to-be Warthog and Marines. The trademarks for "" and "" were filed in March 1998. "Monkey Nuts" was quickly changed to "Blam!" as Jones didn't want to tell his mother he was working on a game called "Monkey Nuts". This integration would be based in the Myth engine, and was later referred to as "basically Myth in a sci-fi universe." This prototype would change name from "Armor" due to the need to avoid the game actually shipping with that title, and would be referred to internally as "Monkey Nuts" as to ensure the game would not actually ship with that title. Due to Bungie's interest in physics to provide gameplay, they wanted the vehicles to feel like vehicles and move on 3D terrain. This side project was the origins of Halo: Combat Evolved, originating as an RTS due to thinking Myth would be better if it were science-fiction and Starcraft would be better without resource management. This project was at least in progress by the time the "Armor" trademark was filed on September 24, 1997. During this time, Bungie only had 12-15 employees in a small office in South Halsted, Chicago, when Marcus Lehto was brought on board to work with Jason Jones on a small "side project" then-known as "Armor". In 1997, Bungie had just finished Myth: The Fallen Lords and was beginning the development of Myth II.
