Altered Beast user reviews :

I played this game nonstop on Sega growing up, it was my faaaave! I love that I can play again! Controls are a little iffy but the fact that you can customize and move them for a better play, is great! So far, so good!

Its the same one we all played as kids… The nostalgia is strong with these sega games! Lol! If you liked them then,you’ll like them now

I agree that this is a very good mobile game, fun and challenging but the controls are difficult; you will be getting hit but your man won’t move.

Great app. Sega Forever baby. However, not worth buying with only 5 levels. Ads can be a little frustrating but hey, cant complain too much because its free. its actually a brilliant strategy. Anyway, i finally ended this game after 28 years thanks to the save feature. Game does repeat but levels are much harder. so if u up for the challange, go for it. but ima pass

Was so excited to play this game and relive old memories. however the controls were so bad that it was basically unplayable. jump only works half the time If enemies come from both sides then forget about it, your game is finished. Just about impossible to escape without losing all your health. The enemies just beat the snot out of you and it’s so frustrating I want to throw my phone across the room

I want to give you fine folks at SEGA one more star, but, can not. The controller support is wonky at the moment. Bluetooth controller, too. I uninstalled, but, am not demanding a refund, because, I’ll be re-installing as soon as you fix the game. Altered Beast IS the classic pack in title with the system! So, I know that this will be resolved, because, Genesis does won’t nintendon’t!!! Fix the controller issue and let me know and I’ll reinstall. All the others worked with my 8bitdo M30.

excellent gameplay. makes mew ant to go and dig up mi old sega genesis and relive those days

This is a great port of alteredbeast. Some people are experiencing issues depending on there phone model. I have not ran into any lag, only sound issues which were fixed in the latest update. My only complaint is there is no custom button layout option. I am using an S5 for anyone interested.

Blast from the past! I grew up with Sega Genesis… I love this! how about Golden Axe next?
