If you are looking for a fast paced, action shoot 'em up you really need to check out Air Attack HD for BlackBerry 10. The game, which is brought to us by Union, is of the classic airplane upwards scrolling style which goes way back to the days of the likes of the Spectrum 48K and Commodore 64.
Clearly things have improved dramatically since the 'good old days' and Air Attack offers fantastic graphics and sound effects. With a choice of planes you move around the screen using touch/tilt or joypad depending on your preference and the plane will fire its guns automatically. However, as well as the onslaught of enemy aircraft there are also many bad guys on the ground so in order to destroy them you need to double tap the plane to drop a bomb.
Your score, health and lives are displayed at the top of the screen - although as the game is so busy you don't really get a chance to keep an eye on them. Fortunately, you can pick up extra health and lives along the way as you destroy the enemy.
For £0.75/$0.99 Air Attack HD is one of the best bargains you can currently get for BlackBerry 10 in my opinion.
