Doomsday Zombie TD is a unique zombie defense game that combines 360-degree tower defense and merge item gameplay. In this game, you are the commander of a walled military camp in the middle of a zombie outbreak. Build watch towers on designated spots to fend off the zombies. Drag and combine towers of the same tier to upgrade it to the next, and make sure to add a new tower on an empty lot. Earn money and use it to increase the tier of your default tower, expand the camp, or upgrade your towers' and workers' capabilities. Building a tower will not require money, instead, it takes time. Merging towers will upgrade the tower's tier and increase the number of shots it shoots per second. Upgrading the camp will increase the wall's hit points and the likelihood of surviving the levels. The total number of zombies in each wave will be displayed in the top part of the screen. Defeating all the zombies will end the wave and will give the commander a chance to expand the camp.
