Galaxy Planet Colonise

Xenidian Mars Attack is live until 31 October: ten levels, one dragon each, free. No adverts, ever.

Take the galaxy back, one world at a time.

The Xenidian invasion was halted four jumps short of Mars. Now the 73rd Space Base hangs at the edge of known space - the last human structure before the far side, and the first one home. A hundred and twenty worlds are waiting out there. You are the colonist they are sending.

ONE THUMB, ONE HAND, PORTRAIT Slide to fly, tap to fire. No virtual stick, no buttons crowding the screen, nothing you need a second hand for. Played standing up, one-handed, in as long or as little as you have.

TWELVE GALAXIES, A HUNDRED AND TWENTY WORLDS Ten planets to a galaxy, and a boss holding every tenth. Clear the waves, take the world, move on. Each galaxy has its own colour, its own creatures and its own map winding up through the dark.

THE NAMES ARE REAL Every one of the hundred and twenty worlds takes its name from a real planet. Look one up.

THE ARMORY Coins are earned by playing, and spent on getting stronger: • Push your colonist blaster up through five levels • Buy and upgrade five special weapons - the Arc Coil's chaining arc, the Plasma Burst's heavy splash, the Ember Thrower's held flame, the Rail Lance's piercing shot, and the Cryo Sling's slowing shard • Unlock autofire • Recruit colonists to fly with

THREE STARS, AND A GOLD MEDAL Clearing a planet is not the same as taking it properly. Every world rates you out of three stars, and a galaxy where you three-starred every planet earns a gold medal. There is a long way between finishing the game and finishing it well.

NO ADVERTS. NOT ONE. No banners, no pop-ups, no rewarded video, no timers asking you to watch something. There are no adverts in this game and there never will be. Coins are earned by playing; if you would rather buy some, you can, and you never have to.

Plays on iPhone and iPad. In English, German, Spanish, French, Hungarian and Norwegian.
