The StarCraft II beta has been going on for a while now, and though it has given players the chance to try out the game's fast-paced RTS action, the beta has also provided an opportunity to play around with the new content editor. Enterprising map makers have been able to work wonders with the powerful tools provided by the editor, making everything from a version of Tetris to an actual first-person shooter. Here are some of the best maps so far.

Tetris

Yes, that's a fully playable version of the ubiquitous falling block puzzle game built out of supply depots. You control the game with the arrow keys, and it even features a multi-player mode, where the goal is send trash to your opponent's screen, causing it to fill up.

Smash TV

It may be a bit awkward—controlling a dual-stick shooter with a mouse and keyboard—but someone has attempted to recreate the classic arcade shooter Smash TV. You control movement with the WASD keys and fire with the mouse, taking out swarms and swarms of enemies. The creator is hoping to have a playable demo ready by the time map publishing becomes available on Battle.net.

Wacky Race

We've all probably wondered at some point just which StarCraft unit is the fastest. Well, one enterprising map creator has decided to find out once and for all by creating a Mario Kart inspired racing map. It looks a little goofy, and it's hard not to feel bad for the poor Thor stuck at the back, but considering this was created the day after the map editor was made available, there's clearly quite a bit of potential.

Bullet Hell

And the new genres don't end there. Someone has also managed to cobble together an actual working, bullet hell-style shoot 'em up, complete with screen-filling attacks and anime-inspired music and visuals. There even appears to be a power-up system in place, as the little fighter is able to upgrade several times throughout the video.

FPS

Arguably the most impressive map so far is a proof-of-concept that turns the real-time strategy game into a first-person shooter. According to the creator, the demo currently features "full, seamless 8-directional WASD movement; smooth mouselook; and a gun attack based on a custom traceline function." Plus, you get to blow up Zerg in first-person.

Diablo III

And if you can't wait for Blizzard's other big release, Diablo III, someone has already created a Diablo-inspired map. It gets the look and style down, with flowing lava and treacherous pathways, but, more importantly, the map features a customized user-interface very similar to what the Diablo series offers.

The sheer range of user-created maps already available is impressive, especially considering the game doesn't come out until July 27. It's hard not to get excited to see what will happen when these tools are available to everyone, not just the lucky few who made it into the beta.
