Random Merge Defense for Android
The player places units across the playing field to prevent the hordes of mobs reach their target. The player's units keep to their position and attack enemies automatically. However, in the course of the game you can get units of a higher level by merging two units.
Units can also get extra equipment that can also be upgraded by merging two identical objects. There are many different units divided into 6 classes and 15 types of equipment.
