User reviews

:)

Loved this game for years. I just wish you could save and place destroyed ship debris and other scenery pieces in sandbox mode.

Kill time

It’s a good fun game RTS to kill time but I only wished there were new updates and new added features and maybe expand more units and fleet etc plus tech to unlock

Disappointed

I prefer the graphics from the earlier version over the cartoony backgrounds it has now. I’m not sure why the developers chose to change everything so drastically, but there should be an option where you can choose between the different graphic styles.

Response from developer

Sorry to hear you are disappointed by the changes we have made. We believe that the original background design was too distracting, i.e. mixed too much with the foreground. Maintaining a set of different backgrounds would make the game larger in size and more convoluted unfortunately. Perhaps you could still give it another shot, it’s probably really just a matter of getting used to the new look.

Great game!

Probably my favorite mobile space RTS games. More levels please!

Excellent RTS

An incredible example of how to do tablet based RTS, customizable ships with a facsimile of fleet formations and several modes of play make for a highly enjoyable, and replayable experience.
