Neon-coloured shooter Super Crossfire HD has just been reduced to 69p / 99c on the App Store.
This fast-paced sci-fi romp clearly takes its lead from arcade classic Space Invaders, but adds an ingeniously simple mechanic to bring another dimension to the gameplay.
You see, instead of having your bullet-spraying spacecraft permanently anchored to the bottom of the screen, a quick tap of your finger warps the ship to the top of the play area.
This nifty ability allows you to turn the tables on your alien foes, giving you the chance to deliver a little 'death from above' for a change.
There's also an upgrade system that allows extra hardware to be bolted onto your craft, and a "Dark mode", which offers masochistic players 150 extra-challenging levels to conquer.
You can grab Super Crossfire HD from the App Store at the temporarily reduced rate of 69p / 99c.
