You're with another team but they split you into pairs, and you and Armin are together. you have to kill all the giants you find, the environment was not pleasant, the sky was grey and it was raining, the large trees were unsettling. You were relaxing under a tree when you hear giant footsteps behind the tree, you turn and a giant is standing there blocking you, you run away when a group of 20 giants are chasing you. You were behind because you were running out of gas.
