In marketing limbo for some time, From Software's Armored Core 4 was recently confirmed as a 360 title. Previously known only as a PS3 title, we welcome it into the 360 fold. The trailer shows off a nice mix of both CGI and in-game footage. Filled with lots of explosions and contrails, it also proves an old trailer making adage, "if you want to make a trailer really dramatic, put a big choral number in it." Check out the (very long) trailer after the break.
