If you have starfore plus you may have noticed that there are two units that arent in either Brood War or Starcraft. Both of these are battle cruisers and they function like heros and you can change their settings. (Arcturus and Dugalle) Now if its possible to make additional units like that, why doesnt some one make an editor with like 5 diferent zerglings, 4 diferent tanks.
If some one could come up with this, it would enhance map making to the next level.
Personally i think this would be a good idea, and if it is already done, why not just expand on it.
No, those units are extra. But, those units are accually in Starcraft's .mpq. You cant just create new units. Its just that those two battlecruisers werent included in the game, but were still in SC. Its like the Terrain Starport ( i think thats what it is called )
