The Name Says It All: Nothing Gets Past This Line
Keep Out puts you in charge of a small protected zone and a shrinking window of time before the next wave of intruders comes looking for a way in. Rather than controlling a hero that fights directly, you're placing obstacles, barriers, and traps in the right spots before trouble arrives, then reacting on the fly when an intruder finds a gap you didn't account for. The puzzle isn't just in the initial setup — it's in noticing which approach paths you left exposed and adapting mid-wave before a single breach turns into several.
Placing, Blocking, and Reacting in Real Time
Click or drag to place available obstacles and barriers on the grid before a wave begins, positioning them to funnel intruders away from your protected area. Once a wave starts, keep watching for gaps and react quickly by placing any remaining resources where an intruder is about to slip through.
- Block the widest, most obvious approach paths first before worrying about narrow side routes.
- Leave a small reserve of obstacles unplaced so you can react to unexpected breaches mid-wave.
- Study each wave's pattern once it starts, since intruders often reuse similar paths in later waves.
- Prioritize sealing off multiple entry points over reinforcing one already-blocked path.
- React immediately to the first sign of a breach rather than waiting to see if it resolves itself.
