Tempest Tank
The Tempest is an Eldar Super-heavy Grav-Tank and like the Deathstalker it has not seen the days since the age of Epic. It is armed with a Pulse Laser, Shuriken Cannon, and Shuriken Catapults.
From what we can gather this thing will probably rape infantry with the amount Shuriken-dependent weaponry it carries around it. Unlike other super-heavies it doesn't use the same chassis as the Scorpion but of course this model came way back in the 1990's so any room of change will happen.
