In Zero-K how do you decloak units? How to see cloaked units?

Solution 1:

1. You do that by walking your unit near to it or forcing it to fire. Since you don't initially know where exactly this "near" is, it is usually done by spawning and spreading a lot of cheap units in strategical chokepoints. Since the clocked units are usually weak in a hand-to-hand battle with a raider, such decloak usually ends up in the cloaked unit being destroyed.

2. Starve the opponent of energy source. Cloak usually consumes power, so denying that power automatically decloaks enough units to compensate.

Remember, that decloaking is temporary, and each cloaking unit will cloak again if left alone and the owner has enough power.
