Obitus is a role-playing game with action elements. It utilizes a first-person view for exploration, similarly to Dungeon Master and Eye of the Beholder. One of the more remarkable features is in the first-person mode: rather than having just 4 directs to face and flicking between them, there are 8 directions and the view scrolls smoothly as you turn. This smooth scrolling continues when you move forward, giving the game more of a 3D feel.

The action elements consist of horizontal scrolling areas where you fight enemies with your bow while avoiding their attacks. Later you encounter a similar type of gameplay that involves exploring castles and adds 4 directional movement.
