Shard walker

The Shard walker was a Reaper-17 variant of the standard Scrin Gun Walker.

Background
Believing the Gun Walker to be an antiquated relic, barely useful against all but the most primitive of species, Reaper-17 developed its own variant of the walker after a prolonged period of ritualistic, Tiberium fuelled experimentation. The result was the Shard Walker, a mutation of the Gun Walker caused by excessive Tiberium infusion. As a result of this mutation, this Walker is faster and stronger. In lieu of an energy weapon, the Shard Walker fires Tiberium shards at high speeds. These shards are stronger than the energy weapon, and the weapon itself is capable of being upgraded to Blue shards. It can also make use of Attenuated Forcefields to increase its durability.

Game unit
Multiple Shard Walkers with the blue shards upgrade can cut down legions of infantry and aircraft with horrendous efficiency. Conversely, large concentrations of Zone Troopers or Raider Squads are fatal to Shard Walkers, they are able to inflict comparable casualties in mere seconds.

Changelog

 * Kane's Wrath patch 1.02: cost/build time increased to $800/8 sec
