Lifeline Ideas

Well for the TD im making (Station TD) your lives will be wandering around your base, and as you upgrade them, they will be able to do stuff for you when they get near other units.

I need unique ideas for what they can do. And not things like "when they get near enemies the enemies will be damaged" or "they have a spell like endurance aura". But keep in mind that you will have no control over them, and as guys leak, you will lose some of them.

Well, I suppose you could make it that they unlock more powerful towers or something. Or perhaps some will randomly create a weakish but useful tower every wave. I'm not sure what you really want if you don't want damage or auras applied to the nearby enemies.

well its not that i don't want to use simple things like that, but that its not hard for me to think up of simple things like auras on my own

Perhaps you could have the lifeunits count up the number of maze-running guys that they get near, and then have them perform certain effects or give better bonuses when they have been near certain numbers of the maze-runners.
