Gameplay The game is played from the first-person perspective, where the player's task is to perform retrieval missions, sabotage or assassinations. Players can be armed with typical WW2 weaponry and can even use fictional weapons such as a German-made minigun or a Tesla gun. Players can also use stealth to eliminate enemies, with some missions strictly requiring for stealth to be used. Enemies vary from standard soldiers to undead and experimental creatures. Health is replenished by collecting health packs and food. Armor also can be collected for additional protection. Multiplayer Multiplayer is an objective-based game mode, in which players are split into two teams—Axis and Allies. Each team has a set of objectives to complete, the Allies usually being to destroy some sort of Axis objective, and the Axis objectives being to defend their objectives. These objectives are split into two categories, primary and secondary. Primary objectives are ones which must be completed for victory, generally stealing secret documents or destroying a radar array; however, secondary objectives are ones which are optional—they do not have to be completed, but if they are they may aid the appropriate team, such as blowing out a door to allow access into a tunnel which shortens travel time or allows less-noticeable infiltration of the enemy base. Each team has access to a slightly different set of weapons, matching those used by each side in World War II. Players can choose from four different classes: Soldier, Medic, Engineer and Lieutenant. Soldiers can carry heavy weapons, such as the Panzerfaust, Venom Cannon or Flamethrower, which are not available to other classes. Medics can revive and heal other teammates. Engineers can breach obstacles and arm and defuse dynamite. Lieutenants can supply ammo to teammates and
