This is my main Armored Core in Armored Core Nexus/Nine Breaker/Last Raven. (I didn't paint it acordingly, like the I have it on my PS2)
Running Nine Breaker in my PC via PCSX2 emulator.
For those who dont know, Armored Core is a series of games where you pilot mechs called [Captain_obvious] Armored Core. [/Captain_obvious]
You earn cash or parts from doing missions and facing rival/friendly ravens in the arena where then you can use the money to buy parts for your mech and costumize it. It's a very tactical game, with some very good stories and a very hard game series.
Before I liked Monster Hunter, Metal Gear Solid or STALKER, I was (And I'm still) a VERY big fan of the series
Recently got Armored Core 3 Portable for my PSP and I just love it!
