Szczury Pustyni (Desert Rats) depicts several battles fought in Libya between 1940 and 1942. Counters and scenarios are for Operation Compass (British victory over the Italians), Rommel's first offensive (pushing the British back to Egypt), Operation Battleaxe (first and failed attempt by the Allies to relieve Tobruk), Operation Crusader (successful Allied attempt to relieve Tobruk) and Battle of Gazala (Rommel's second thrust that reached Egypt).
The game uses simplified rules of the B35 (Battles of World War II 1943-1945) system designed to simulate medium battles of World War II with some additional rules too, dealing with specific aspects of desert warfare. Counters represent battalions, one hex represents 3000m, one turn represents one day.
