Ultimate Doom is the answer to all your requests to combine the three mods of the Doom series - Doom Dragoon, Terran Doom and Zerg Doom - into one StarCraft mod so you can play it against your friends! The Doom series was created to demonstrate iscript-based modding techniques and so you'll see a lot of what iscript modding is capable of in this mod. You'll also find a whole lot of new effects in this mod as well, ones that weren't seen in the Doom Dragoon, Terran Doom or Zerg Doom! In this mod you'll find a whole slew of effects. Photon rain, arclite sprays plus psionic vortexes, psionic radiation, trampling Ultralisks and more. The mod is designed to give each unit a little bit of a kick while retaining their original purposes in the game so you can play it as normal. Great for playing melee against your friends!
The photon cannon now uses a new photon rain
attack which damages all units in a certain area.
Plus it's very cool-looking.
