Given the popularity of Vlambeer's (or Not Vlambeer, the studio's alternative label) Super Crate Box, and not to mention its work on the upcoming Serious Sam: The Random Encounter RPG, it's surprising that the Dutch developer couldn't find a sponsor for Luftrauser.

Vlambeer says the game was "too extreme" for sponsors and has decided to release Luftrauser for free -- it's available right here for you to load in your browser, and jump into a huge aerial dogfight that pits you against an army of enemy aircraft and ships.

There's not much to the game, but what's there is fun. You can take a few hits, repair your craft by not firing, and rack up a high score by taking down as many enemies before you're overwhelmed. You can then submit your score to online leaderboards to compare.
