Blacklight: Tango Down is Zombie Studios' digital download title for PSN that's looking to give punters a similar level of quality and content as a full-fat retail title at a fraction of the price.

This latest Blacklight developer diary examines the game's deep weapon customisation system, which caters for all manner of unique combinations for your arsenal, with different muzzles, butts, magazines, tags and more.

Apparently, the amount of customisation options will allow you to create a huge number of different weapons, enabling you to build a gun that's individually suited to you.

Blacklight: Tango Down is out on PSN in summer 2010.
