Troubled by the poor quality of life and the excessive amount of damage inflicted on Earth, they decide to plant new colonies on distant planets. The Earth military (EDF or Earth Defense Fleet) is in charge of organizing and carrying out this immense project. During the colonization, the EDF encounters a new life form, which turns out to be extremely hostile. Multiple attacks on EDF key installations, as well as on a research ship, force the EDF to improvise new strategies for a full evacuation. You are a high ranking officer of the EDF, who is in the midst of all the action. Make sure you all get back home to Earth safe & sound.

One of the best RTS games on iOS

Let me start by saying I have played a TON of RTS games on iOS. in fact I have played a TON of different games on my iPad in General. I came across this game when I did a recent search for a space RTS (I had just finished playing GOF2 for the 7th time). I can safely say this is one of the most underrated games I have found in the App Store. The game play is pretty in depth, and the story is short but entertaining.I would love to be able to create larger fleets, as I have more resources than I have available ship slots. But a 5 star game non-the-less. If you're a fan of games like Star Trek Armada, or any other RTS that centers around big battles and resource gatherings his is a must have on iOS! I got the game about 2 days ago, and just beat the campaign. As soon as I finish writing this review, I'm going to purchase the expansion. Overall this a great games and I'm looking forward to updates!

Best RTS Game on IOS EVER!

I LOVE this game so much! For a small price you get 9 incredible and in depth missions, a fleet you command across said missions to combat a powerful foe, multiple different modes including a conquest mode DLC which adds a lot more content, and tons of FUN and DESTRUCTION and Replayability! The conquest mode DLC is only 1 dollar but in my opinion it’s worth more than that. OH and a sandbox mode where you can do just about anything you want!! It even runs incredibly on my very old iPad mini 2 at 60fps!

Best RTS game on IOS EVER! I Can’t wait for a sequel :)

Crashing on iOS 11 on an iPhone 7

Let me start off by saying this looks like a great space RTS. It’s a game category that’s hard to find good games for on mobile platforms and I think Space Borders has a lot of potential.

My largest complaint by far is the crashing. I might be 30 minutes into a single battle and the app will crash completely. There’s no option to restore progress either—you have to start over completely. After three crashes in a few hours I gave up.

The other complaint I have is with the resources. It is possible, in the beginning of the game, to buy things you don’t need (like a mining ship) and then not be able to purchase any weapons. If you keep selling things back and taking a 50% cut there will come a point where you can’t actually purchase anything else or restore your inventory. You need weapons to get resources and the first few levels are pretty difficult even with a decent setup. There’s no hard reset save uninstalling and reinstalling the game.

Developer Response ,

Thank you for your feedback. I am currently looking into potential causes for the crashes you are experiencing. Hopefully, things will be patched up soon. Sorry for any inconveniences this might have caused.
