Leif Bloomquist released his game Vortex 2 for the testing phase. This game can use the internet to play against another person. In the game you can fly with your ship and shoot at the enemy, but nothing will happen at this stage in the development of the game. The game is auto-updating. You need an RR-Net or compatible cartridge (64NIC+, FB-Net, etc) for your C64 or you can use the VICE emulator. For more informations visit his blog.
