Bubble Tanks TD
Bubble Tanks Tower Defense takes Hero's popular series into new genres and beyond! With 7 enemy types, over 11 unique tower paths, tower merging allowing for mega towers and mega-mega towers (the size of 16 towers combined!), and 52 whopping game modes, we're pretty sure you'll have plenty to keep you busy until the release of Bubble Tanks Arenas. :) If that's not enough for you, just check the "FML" checkbox from level select and prepare to get your world rocked... er... blocked.
Full tutorial and instructions are in game. Can be played using only the mouse, but hotkeys are suggested for experienced players. Hotkeys can be changed via the Settings menu.
