11 bit studios has announced its upcoming title, Anomaly Defenders. The game will be the final installment in its Anomaly series of tower offense games.

Anomaly Defenders will be a unique shift, in that the aliens are the attacked party and humans need to be neutralized. The developer refers to the game as the “first ever Reverse Tower Offense game.” It will entail making tactical decisions in real time. Towers have different abilities, and units react to different towers in different ways.

There will be 24 levels with adjustable levels of difficulty. Anomaly Defenders is due out later this Spring.
