A space soldier stalks a maze dungeon full of monsters. Grubs always show, but Shades and Fangs fade out of sight — only the radar below gives them away. Every monster you shoot calls a nastier one. Use the side doors to warp across (they slam shut behind you), catch the fleeing Wisp for a double-score dungeon and survive the teleporting Warlock. Free, no sign-up — play right in your browser.
