What is the eraser trick mentioned in this StarCraft video?

Note: This is referring to the 1998 game, not the current game.

    You shouldn't have to add that "Note" on every question. The whole purpose of a [starcraft] tag instead of a [starcraft-2] tag is to establish that you're asking about the 1998 game, not the new release. Anyone who answers you otherwise is not actually reading your question.

    Funnily @Grace I tend to misread that and aim for Starcraft 2 :$

    @Grace, I shouldn't have to but I get SC2 answers when I don't.

    Make the tags [starcraft-1] and [starcraft-2]? That would eliminate any ambiguity I think...

    @Shaznat but the name of the original game is starcraft, not starcraft 1. Nitpicking, I know, but I think we should stay as close to the original name as possible - after all, we can't know when a reboot will appear :(

1 Answer 1


Here's a summary of what it does:

"Doing the Eraser trick is very easy, you only need two or more Science Vessels with Irradiate researched. To do the trick, simply have your two Science Vessels irradiate each other, and fly them over or near the units you wish to kill. Since Science Vessels are not biological units, Irradiate has no effect on them; however, Irradiate's splash damage hurts surrounding biological units."

  • It's worth noting that Science Vessels have a fairly wide radius (which affects the area of damage) as well as decent speed, so they are perhaps the ideal air unit to irradiate.

  • @JoeyAdams I think it's more about convenience in the SK Terran build order. If you're massing science vessles, it's hard to have the gas and Starport time to build other air units.

    @JoeyAdams "Irradiate is an offensive spell cast by the Terran Science Vessel and surrounds the targeted unit with an aura of radioactive energy. It can be cast on any unit (unless in Stasis) and deals an equal amount of damage (250) over a period of 37 in-game seconds to all biological units within a 2 hex radius of the affected unit. " (from Liquipedia). SV's sight radius doesn't impact the damage dealt by an Irradiate spell cast on it. Feb 12, 2014 at 16:25
