Fight your way up a scrolling jungle on foot. Run in eight directions and your rifle fires where you face; grenades arc over sandbag walls and crack concrete bunkers. Riflemen rush in from the top and the flanks, gunners crouch behind cover, grenadiers lob back and motorbikes race across. Free the prisoners being marched past, then hold off the garrison that pours out of the fortress gate at the end of every area. Free, no sign-up — play right in your browser.
