I bought this yesterday and it's the best game I've played on iOS in a long time. Well worth £1.99. No in app purchases, no log in rewards - gaming as it should be. Gets very good reviews as well.

Note it's still in development at the moment and only episode 1 is available. Eps 2 is due to have a release date announced soon, and there will be 4 in total. Each additional episode will unlock at no extra cost, so it's £1.99 for all 4

Also available on PC, but much more expensive, and due on Android at some point.

Blurb:

Ticket to Earth is a sci-fi tale of betrayal and insurrection. The mining boom has left New Providence to die, and just one Earthbound ship remains. Survivor Rose stands in defiance of a broken system. Rise up with fast-paced RPG tactics, and battle across vibrant fields of color.

Join the fight in Ticket to Earth.
