Map name on BNet EU: "Temple Arena BETA"
Concept
Temple Arena is a map based on the concept of arena maps like Marine Arena, Footmen Frenzy or similar but with completely individual game mechanics and a lot of new stuff including a brand new landscape. Your goal is to defeat the opponent teams by destroying their headquarters. You have to use teamwork, effective unit compilations and upgrades aswell as macro and micro skills to win this game.
How to play
You can choose from 6 different mercenary classes and 3 basic unit classes to get your desired unit mix. You might aswell add one of currently 6 available heroes to your army to support your units in various ways. Additionally, you get an enormous amount of upgrades for your units and heroes.
Training mercenaries itself doesn't cost you anything. You have to build an appropriate training building before though, and this costs minerals depending on the unit. Minerals are rewarded for killing enemies. Basic units are trained in your headquarter and therefore no extra building is needed.
Within the map there are some strategically important points. 4 obelisks to the north, west, south and east give minerals to the owning team and in the center you can find a xel-naga watchtower.
Game Modes
Currently it's set up as a 2v2 map. The next updates will add support for two additional teams (2v2v2v2 mode). In the game itself you can vote like any other player for specific game settings like starting minerals and similar.
BETA
The map is still BETA so a lot of features are not fully implemented yet and there might be bugs too. It's already playable though. I'm currently looking for beta-testers on the EU-Realm
