In Medal of Honor: Allied Assault, the first PC installment of the famous Playstation game series, you assume the role of Sgt. Mike Powell, a member of the 1st Ranger Batallion. You have been recruited by the OSS (some sort of secret service) and need to battle through over 20 levels based on historical campaigns during WW2.
Missions include the landing at Normandy (D-Day), assaulting the town Arzew, a rendez-vous with the french Resistance outside the village of St. Lo, and even taking the famous bridge at the German town Remagen. You will need to rescue agents, plant explosives, assault desert camps with your team and of course kill every Nazi that comes into your gunsight.
There are plenty of weapons available, including the MP40, some sniper and assault rifles, hand grenades and explosive charges.
