I've been playing Zero-K for a while now, and I've noticed that most of the relatively strong defensive structures can only attack one enemy at a time.
I think it would be really interesting to have a defensive building with a short range, but capable of simultaneously firing powerful lasers at around 5–6 enemies at once.
To balance it, its range could be significantly shorter than other defensive structures, and its build cost could also be higher.
I think this could make it useful against groups of units while still keeping it balanced because of its short range and high cost.
