🗼 Reef Wall Campaign

Reef Wall Campaign is a merge-to-defend strategy game set at a coral wall in the deep sea. Buy cheap level-one shooters into a 5×3 grid, then drag two of the same level together to fuse a far stronger one — that merge loop is the whole engine of your defence. Your shooters auto-fire up their lanes at the foes descending toward your wall, so victory is about smart merging and lane coverage, not twitch aim. The mode is Campaign: clear a fixed run of waves with a boss finale. Coins drop from every kill and a bonus lands at each wave break; spend them to buy more shooters to merge, and watch out for the heavy boss that storms in every fifth wave. A tip worth remembering: save the wave-break to merge and reposition before the next push lands. Survive to the final boss wave to win the map. It runs instantly in your browser on phone or desktop with drag-to-merge controls, crisp canvas art, WebAudio sound you can mute, pause and a one-tap restart, and your best wave saved locally — no download, no sign-up.
