The Imulsion is rising and you'd better find higher ground. Take look at some direct-feed video of the Flood map included with the Combustible Map Pack bundle for Epic's Gears of War 2.
"Flood is a very tight map that's made extra snug when Imulsion starts creeping up around the edges. As the playing field closes in, the firefight intensifies and combat is forced to the center of the map. Take cover, keep your eyes peeled, and remember to head for high ground."
Gears of War 2 and the Combustible Map Pack is available now for the Xbox 360.
