Here's an alternate tower defense game mode for the game I have in the works. Take a look and tell me what you think. The main game is still way off, maybe two or three more years in the works.

How to play:

Capture turrets and spawn worms to defeat the enemy. You win when one of your worms reaches the enemy base. Capturing a neutral turret or destroying an enemy turret or worm will give you a point. Spend points to spawn various worms. Capture generators to produce points to upgrade turrets, worms, and player. Your spawned worms will also capture neutral turrets if they pass by them.

Controls:

WASD or arrow keys to move. Left-click to shoot. Right-click to claim turrets. Tap CTRL to control robot drone. TAB to leave menus. ESC to reset/quit.
