Objectives include sabotage, infiltration, capturing certain objectives. Most missions in each campaign include the player blowing something up, killing a certain number of enemies, stealing enemy intel, and then sometimes returning to a certain location to escape. There are three different levels to be attained in each level: bronze, silver and gold. To score bronze, the player must complete all primary objectives. To score silver, the player must complete the primary and secondary objectives. Gold is the same as silver but the player must have high accuracy and kills. Obtaining these different levels increases the player's rank and helps the player complete the game to 100%. Through gameplay, players may unlock skins to use in multiplayer and skirmish mode.
