Merge Monster Attack

Tap on the screen to choose your initial weapon. Drag similar weapons together to combine them into a upgraded version. Plan about which weapons to merge, as each attack round requires a unique approach. Guard your base by launching at enemies before they arrive at it. Pay attention to enemy characteristics, as some may demand special weapons to defeat. Progress through levels by defeating all enemies, and gain new weapons as you go. Adapt your strategy as the game becomes more challenging to last longer waves.
