On 1st May, indie space blaster Velocity became available to download exclusively for PlayStation Plus subscribers and promptly shot straight to the top of Metacritic's list of top-rated PSP games of all time. It's now out on general release worldwide, and you could do a lot worse than spend four of your shiny pounds on this fantastic arcade-style thumb twister. Developed by indie studio FuturLab and boasting a thumpingly glorious soundtrack co-written by Killzone 2 composer Joris de Man who also scored that other frustratingly brilliant indie gem N+ - Velocity has accurately been described as arcade perfection, amongst numerous other accolades that have seen it being lauded as the best PS Mini game yet. Velocity's retro graphics betrays its Galaxian-style arcade roots, but it's the game's perfectly balanced controls and finely honed gameplay that raises it above the glut of pixellated indie games currently on release. A well-thought-out concept adds a further layer of depth: you have the ability to teleport around the screen, and later in the game you can drop teleport pods that allow you to return to earlier parts of levels (the screen scrolls relentlessly upwards, forcing you to zip around as the level design gets progressively more complex). Deftly balancing multiple genres shoot-em-ups, exploration / puzzle games and racing games Velocity punches high above its weight in terms of engaging gameplay, but most importantly it's also highly addictive and fiendishly challenging I still haven't got past that last level! Velocity is available now on the PlayStation Store for PS3, PSP and PS Vita, and costs £3.99. Check out our review for more info.
