The manual control mode of the crew member (called by pressing the Spacebar) allows you to control the character as in some top-view shooter games.
That is, you can play directly as a crew member, shoot aiming with the mouse and run in different directions (WASD keys) as well as use different objects - open boxes, start dialogues with NPCs, use ship modules.
In this regard, the game combines several genres:
-Strategy (controlling units by selecting them with the mouse and giving them orders)
-Action (when you directly play the character)
