The 6th gen is the 128-bit era, this is the time of the ps2, xbox, game cube and sega dreamcast, there was apperintly another console called the XaviXPort but i never heard of it. This era ended arounf 2005 when the xbox 360 came out.
If you guys loved CONTRA from NES then you will know the title ... YES contra for playstation 2
Hrr, no matter the story, just pick your PS2 controller, start, SHOOT!!!
