Plenty of non-stop, progressive action with over 65 waves spread across 3 levels featuring a huge variety of different enemies each with their own unique behaviors along with final bosses to bring it all to an explosive finish.
Coupled with amazing special effects, leaderboards, 24 achievements to unlock and an amazing musical score, Alpha Wave delivers solid quality for far less than the price of a cup of glorified, high society coffee!
