Merge Monster Attack

Click on the screen to pick your initial weapon. Drag similar weapons together to merge them into a stronger version. Strategize about which weapons to merge, as each enemy wave requires a unique approach. Guard your base by firing at enemies before they arrive at it. Watch out for enemy traits, as some may demand special weapons to defeat. Move forward through levels by beating all enemies, and unlock new weapons as you go. Modify your strategy as the game gets harder to survive longer waves.
