11 bit studios s.a. has unveiled a video announcing Anomaly Defenders, which is labeled as "the first ever Reverse Tower Offense game". Anomaly Defenders puts you in charge of alien machines defending their homeplanet from ruthless human invaders. You will build towers in strategically chosen designated spots. And you can develop and upgrade unique tech trees to increase towers' efficiency.
