They still make 8-bit games in year 2010
You take charge of Rusty, a military expert who is sent to close alien portals, The Void and save the mankind. Everything in the game follows a 8-bit look and feel. Graphics follow simple late 80's 2D look, not like current 2.5D games but really two dimensional graphics what NES delivered. In fact in start of the game there is a NES cartridge that needs get blown-in for game to work. Sound is chiptune music for that particular era.
Of the three versions: DSiware, iPhone and this Steam version the controls are worst since keyboard is to be used. There is a game-pad support for this version which probably would make it easier. Game consists of only three chapters with a boss fight in the end. Each chapter follow Metroidvania style platform/shooting combination. Task is to find a key card to unlock the last door in the level. In mean time shooting and avoiding lava lakes and so on. Level design is well done and progression is well guided. Despite the first level that has some back tracking. There are also 100 energy thingies to be collected and secondary quests on each level.
Dark Void Zero can be easily be finished in a hour if you are skilled. Although three different difficult levels, Steam achievements and leaderboard scores add good amount of length. Despite this one is left wanting more after the game. Good thing about the game, except for the solid 8-bit platform game play is that this is netbook friendly and at £2.99 doesn't really hurt your wallet.
