This is just another Site where you can find some free games.
This page will not be updatet too often. Maybe twice a year
But you will find at least one new Alpha release at every update.
The games on this site are written for Windows and they need an openGL driver.
A pure software implementation is buildin, in Windos95b and later.
But I strongly recomend an hardware driver for your videocard.
From here you have following options:
Read the News
Look at the game: Another Conquest
Look at the game: Another KrakOut
