in 1944, the Rat Bastards are thrown into battle against the Imperial Japanese Army at Driniumor River, Western New Guinea.
Whoever controls New Guinea can turn the tide of the war. That's why the Japanese 18th Army, lead by General Adachi, are mounting a bold sneak attack designed to wipe out the Americans.
But the Rat Bastards know when and where the enemy plans to strike. Can they quit thrill-hunting and fighting each other long enough to become the killer combat unit the Yanks need to survive? They are going to make sure a bigger, bloodier surprise is waiting for them!
