Lost Planet 3

Using the game's mission-based mechanics, players can choose to take on core quests that progress the story, or side-quests to help out fellow colonists on the planet. The game will allow players to openly explore areas in a style similar to role-playing games with the ability to talk to non-player characters, obtain side-quests, upgrade equipment and build their own bipedal rigs using items gathered throughout the campaign.
