'HOT PXL' is a collection of micro-games themed around street culture and the digital lifestyle. The rapid fire game play requires players to draw on their old-school arcade prowess to get through hundreds of inspired scenarios. Whether it's blasting through an old-school, Zaxxon-inspired game, busting tricks on a massive skateboarding half pipe, stage-diving at a pixellated concert or simply trying to cross the street.
By playing through the regular game (Story Mode), players unlock new options and alternate versions of the micro-games that encourage social play. 'HOT PXL' will take full advantage of the PSP's unique capabilities, including the ability to download new content through a PC interface, ensuring hardcore and newbie gamers alike receive the most colourful and original gaming experience around.
