Hexage has decided to update their popular retro-style Pacman-esque game EVAC (and EVAC HD) with some new levels and more importantly release it for free! Our esteemed editor reviewed the game some time back and he was particularly impressed by its "magical" soundtrack.
According to Droid Gamers, both versions of EVAC are completely free and contain no ads whatsoever. It seems as though Hexage has decided to adopt a freemium model whereby they will offer in-game purchases that can be used to pass difficult levels, extend the number of lives, and obtain longer lasting power-ups. However, these in-game purchases are "completely optional and the game is playable from start to finish without spending a penny".
This seems like a great deal considering the game is incredibly addictive and this latest version brings with it a number of interesting levels.
