What playing Dr. Chaos is like
Action-adventures blend real-time combat with exploration, puzzles and item collection. You open up a larger world gradually as new tools let you reach places you couldn't before.
Tip for newcomers: Keep a mental (or paper) map of locked doors and unreachable ledges; most action-adventures expect you to come back once you find the right item.
