To quote the website, "NAEV is a 2D space trading and combat game, in a similar vein to Escape Velocity.
NAEV is played from a top-down perspective, featuring fast-paced combat, many ships and outfits, and a large galaxy to explore. The game is highly open-ended, letting players proceed at their own paces."
There's a handy package available at PlayDeb and downloads are also available at our Google Code page.
Gameplay videos are at Youtube, both early and late game. Recorded with glc, which is an awesome piece of software.
0.4.0 is fresh out of the oven, released on September 18th. The Changelog is available for those interested.
Code and data are, of course, completely free. GPLv3 code, various licensing on the media (GPLv2, GPLv3, PD, CC-By (and -SA) 3.0).
Our primary communication method is IRC, #naev on Freenode.
