Once you are ready, choose from two campaigns: desert and alpine. Review your objectives before each mission on the briefing screen, and prepare for battle against an onslaught of plastic troops. A mission will fail if you exceed the time limit, allow your rivals to win, or let Sarge die. The options screen lets you view current objectives, consult a strategic map, exit vehicles, and abort your mission. You can also adjust the control scheme, select a difficulty level, and toggle music.
