🗼 Mech Bay Bastion

Mech Bay Bastion is a merge-to-defend strategy game set at an automated factory floor. Buy cheap level-one shooters into a 6×3 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: buy two level-1 shooters and drag one onto the other to fuse a level-2 — merging beats buying for raw power. 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.
