The ideas for exploding bots, and for mines are brilliant. I applaud you guys.

There was little detail on AoE weapons with the ability to project into targets, however.

I would like to suggest that each major weapon type be given a different form of AoE attack, making formation choices different depending on the types of bots you are using and the types you are fighting.Here are some examples.

Aoe missiles that explode on impact, dealing damage in a circle from the target hit.
Aoe lasers that strike all enemies in a line that passes between the target and the shooter.
Aoe magnetic guns that ricochet to nearby units a certain number of times.
Aoe firearms the fire a cone of shrapnel centered on the target and originating from the shooter.

These examples are based on the theme of the weapons, but also are related to the current strengths and weaknesses of the weapons.
