The latest title from developer SwanAngel, The Lost War is a first person shooter with a difference - you play a hovering robot (think R2D2) with massive arsenal and the idea is that you blast the heck out of other hovering robots which approach over a futuristic landscape. Gameplay (even after a few app updates) is a little quirky, thanks to the auto-fire system and the hovering mechanics, but The Lost War is lifted into consideration by the stunning beauty of the graphics and the digital audio effects.

From the Store description:

• Graphics intensive game, beware of overheating

Here's The Lost War in action:

Animated intros to each level show off the 3D graphics and context - hovering spaceships (which you eventually get to shoot down - hoorah!)

Your hovering, armed robot - note every opportunity to dim the lights and show off all the Unity lighting/particle effects!

With each level, the opponent AI goes up and the armaments increase...

The landscapes are terrific...

With sci-fi opponents inbound, your two thumbs control orientation and position (these can be switched in Settings), with auto-fire towards the central cross-hair....

On a later level, time to take aim at the alien transports?

It's a fair cop, my reflexes, aim and patience only let me get a few levels into The Lost War, but hopefully you'll do better? You can try/buy The Lost War here in the Store.
