Mech Bay Tall Grid

Merge auto-firing shooters and defend an automated factory floor. Free, no download.

How to play

• Tap an empty grid slot to buy a level-1 shooter (costs coins).
• Drag one shooter onto another of the SAME level to fuse a stronger one.
• Shooters auto-fire up their lanes — keep every lane covered.
• Spend coins from kills and wave bonuses to keep merging up.

Why you'll play it

• Endless mode — survive an endless rising tide and chase your best wave.
• 4×4 merge grid with up to 10 fusion levels.
• Mech Bay theme: an automated factory floor.
• Auto-firing lane defence, coin economy, boss waves every fifth round, infinite scaling.

One quick tip

Hold out as long as you can — the waves never stop scaling. Merge aggressively, cover every lane and focus the boss waves.
