Merge Monster Attack

Click on the screen to choose your initial weapon. Drag similar weapons together to merge them into a more powerful version. Plan about which weapons to merge, as each opponent group requires a unique approach. Protect your base by firing at enemies before they get to it. Watch out for enemy traits, as some may demand particular weapons to defeat. Move forward through levels by overcoming all enemies, and unlock new weapons as you go. Adjust your strategy as the game increases in difficulty to survive longer waves.
