How to Play Shamus
Quick start
Begin in the laboratory and practise moving through the first rooms while firing in different directions. Clear enemies from a safe distance, then explore open exits and note the numbers on keys and locked passages. Touch a key to collect it and the matching keyhole to open the wall. If you hear the Shadow’s low pulsing warning, leave promptly instead of trying to finish every enemy.
Controls
D-pad: move in eight directions. Press A and use the D-pad to fire Ion-Shivs in the desired direction. Only two shots can remain on screen at once, so aim before firing again. Pick up keys and activate their matching numbered keyholes by touching them.
Shamus — About this game
Each numbered key opens its matching passage, making route memory as useful as quick reactions. Robots behave differently, and only two Ion-Shivs can be on screen at once. Clearing a room on its first visit earns a bonus, but repeated visits do not keep awarding the same enemy points. Mystery pickups can provide points or a life, yet can also summon the Shadow; ordinary shots only stun him until the final confrontation.
