Ya, i think it was on the USA Boss, it was hella cool, it took out a GLA command center in 1 strike, hole & all. But it took about 6:00 game time 2 use, but for a more detailed description, try this on for size.
The Ion Cannon is used as a Particle Cannon substitute, the shot is much like that of a Particle Cannon, but much wider, upon impact, the Ion Cannon makes an EMP-Patriot-like explosion, but on a much larger scale, although the explosion doesnt render enemy buildings useless, the Ion Cannon is a force to be reckoned with.
Made that up right on the spot, tht'll give u an idea of what the Ion Cannon is.
Wait a second, who voted no? Whoever did, discuss y u think it shouldnt, balance? 2 many superweapons? Just dont vote no and not discuss ur opinion
