CosmicBreak is an MMO third person shooting game that can go up t0 30 vs 30 in arena battles (wow talk about all out war <_<)

Many mechas to choose from and you can even customize/tune their parts.

I've only been playing it for 2 days but I'm enjoying it ^_^ (Open beta that is. And it will be over in Oct 17)

Well there will be a US server that allows other countries to play in their server and here is their site:

http://www.cosmicbreak.com/

basically there are 4 types of Mechas: AIR, LAND, ART, and SUP

AIR: mechas that can soar the skies longer than any other mechas
LAND: The fastest mechas that walks/runs in the ground and the best in melee combat
ART: Three word: Heavy Arms Custom ^_^
SUP: Your medic in the field. They can even inflict some status effect on other players

But these mechas also comes in sizes: Small, Medium Large

They're size affects what weapons/parts they can equip but basically bigger = more HP

There are more things to say but just try and play it if your interested and here is the trailer:

Well the game aside I really remember reading a manga about this but unfortunately it's name is not cosmic break so I'm still searching the whole compilation of mangafox (and to make it worse it's not in the mecha tag <_<). The reason I remembered about the manga is because of this trailer about 2 of the mechas in the game:
