I don't usually watch sc2 replays but this one is so epic! It's a game versus TT1 and MasterAsia that lasts an hour with a lot of action! It's commented by HDStarcraft and is really worth to see. You really want to stay up to the end :)

Driving System by HaggisNZ

HaggisNZ just released a proof of concept map about cars. He made a driving system using physics law that looks really nice. If you want to impress your players, just add it inside your map :)

Mercenary Battle by Redfox777

Redfox is working on a heroes + lane map that is really promising. He says that's a DotA-like map but: I am making it faster and giving it a more "actiony" feel to the game (more haloish you could say). Matches will be shorter, death time will be shorter, there are man cannons at the bases to shoot you into battle quicker and the map is much more open. All items are consumables and spawn on the map in specific places like they would in halo.
