Catalyst is a tactical nuke launcher and one of Cortexes signature units, unique in its function.
Built by all T2 land/air cons it can strike with light nuclear missiles within a huge range. It is able to overshoot all T1 and T2 defenses so it serves a great role in dismantling heavy defense lines and destroying strategic targets such as Pulsars.
A skilled player may even use it as a defensive unit. If you can extrapolate where incoming units are going to be located 10 seconds from now – you can hit them with an unexpected lethal strike. It stockpiles 1 missile in 75 seconds.
When self-destructed, Catalyst explodes almost like a regular nuke. Use it as a last resort weapon when you know you can’t hold the defense line.
