Following the explosion of the sub, Murphy escapes with his newly bitten blends, chiefly Dr. Merch and 10K. Warren, Doc, and Addy, having just jumped into Escorpion's truck, are taken prisoner by a group of Pan-Asian soldiers. Their leader, Dr. Sun Mei, orders an airdrop of equipment but it lands miles away, setting off a race between the soldiers with our heroes, several groups of survivors, and hungry zombies. Game on.
