Forerunner Tank

The Forerunner Tank was a proposed vehicle eventually cut from Halo: Combat Evolved.

During the later development of Halo 2, a campaign level known by the similar name of "forerunnertank" was developed and eventually cut from the game.

Description
The Forerunner Tank, as intended for the first Halo game, was concepted by Marcus Lehto as a heavy vehicle intended for use by the Forerunners. At this point in time around 1998, the Forerunners were little more than an idea, though the intention was for the Forerunners to still be alive in the active setting of the game. Lehto designed the tank to contrast the art direction of the existing Covenant and UNSC tanks, with the tank designed with a focus on asymmetry and unique forms. Lehto visualised the vehicle as coloured an "off-white" like an "old skull", with weathered "dried blood-red" accent colours.

When firing, Lehto visualised that the vehicle would fire a short-burst energy beam projectile, with an additional burst emitting from the back of the vehicle to counter recoil.

Ultimately, a vehicle similar to this concept was modelled and implemented during the game's early RTS builds, and can be seen in several officially-released screenshots.
