Alien Troopers are a deleted Covenant species seen in the Halo 2 Collector's Edition disc. It is unknown exactly what this seems to be. The only data known is that it carries its weapon under its belly, and was a precursor to the Hunter in this aspect. It bears a small resemblance to Sangheili.
- The Trooper looks as if it could have been conceived as another Lekgolo form.
- Several versions of this alien can be found in the book The Art of Halo. According to the book, the Trooper was meant to be a sniper.
- It had progressed into the texture stage of development before being scrapped, according to art director Marcus R. Lehto in the "cutting room floor" segment of the Halo 2 Collectors Edition Bonus disc.
- The Alien Trooper resembles a mix between a Sangheili and a Jiralhanae.
While developing the Halo games, Bungie, 343 Industries and Ensemble Studios have had to cut some content, such as vehicles, gameplay, and story elements, from the final products. Much of this content has been confirmed by videos and commentary in special edition DVDs, interviews with developers, and released concept art.
