This is a re-make of the game Onslaught Tower Defense, made to be less resource intensive and add new features such as achievements and coins.
This games is not complete, but it is playable. Currently you can choose one of 9 maps in the yellow and blue squares, choose the number of waves, and begin playing. You can build 3 towers and they will proceed to attack enemies that come in waves of 10 until all waves are done. Click next wave when all the enemies from your current wave are on screen to advance to the next wave, or when the 20 seconds are up or when all the enemies have been killed. Clicking towers will allow you to select them, and from there upgrade damage, rate of fire, or sell the turret. I'm working on adding the ability to upgrade range, move turrets, have more achievements that unlock abilities, widen the store, and adding more towers. |
