Do you like multiplayer First Person Shooter games? How about free ones? Sauerbraten (a.k.a “Cube 2″) is a freely available FPS that’s available for Windows, Mac OS X, and Linux.

Sauerbraten has great online multiplayer gameplay, featuring several modes of play, such as Regen Capture (an addicting Capture-the-Flag type of match), Instagib, and Cooperated Edit. And you can play “normal” FPS mode too.

The game has an amazingly easy to use level editor integrated. Nearly everything in a Sauerbraten level is made from varying-sized cubes. The cubes can be stacked, punched-out, textured, and molded into non-cube shapes to build pretty much anything you want. You can add place water, lava, glass windows, invisible barriers, ammo, powerups, flags for Regen Capture, etc. to the level. If you get bored editing maps by yourself, you can take it online, or just across a LAN, with Cooperated Edit. There’s no way you can imagine the chaos of ten people editing the same map at the same time.

Sauerbraten is a very well-made game, reminiscent of Quake III, as some have said, and it’s highly addicting. The game’s two strongpoints of multiplayer gameplay and editing earn it a Knights of the Joystick rating of 4.5/5. There’s still some room for improvement, but the open source community will see to that. Open source packages are constantly evolving, and I have no doubt that Sauerbraten will become even better in the future.

The trailer for the 5th Harry Potter game is now available. You can watch it here. The game will be available for XBox, PC, Playstation, Wii, GBA, PSP(?), and Aspyr will probably port it to Mac eventually. On the Wii version you use the Wiimote as a wand, doing various motions to cast different spells. There will be 13 spells which will be used for dueling and interacting with your environment (you can levitate and blast nearly anything). For screenshots of the game, you may want to look at the Site of Requirement Gallery.

From what I’ve heard so far, this game will be far better than any of the previous games. You will be able to play the basic storyline, but there’s also an “Endless Day” function where you can explore Hogwarts and do things for a long time. Electronic Arts claims that mode may entertain you for weeks. We’ll see about that.
