Gameplay of European Assault is similar to that of its predecessor, a first-person shooter; however, the weapons and interface have been slightly upgraded to be more player-friendly. Most notably the HUD has been upgraded to indicate primary and secondary target and show other squad members, and ironsights were added. The addition of Adrenaline Mode, activated by killing numerous enemies or scoring headshots, allows the player to be invincible and have unlimited ammo for a short period of time. As with all Medal of Honor games, the player is presented with a wide variety of weapons and stages pertaining to World War II. The game was the first in the series to feature ragdoll physics.
