It's a remake of a Brood War map: "Crystallis" I loved this map since it's a great challange to play on it. You must "dig" to the gaysers to get gas.. otherwise you can't reach your opponent only if you dig a way through the minerals which takes too much time. I improved the map a bit to be more like a Starcraft2 map instead of an old-school kind of. You can either drop units into your enemy's base (after you mined gas) or make a way to the big debris heap at the middle of the map and with destroy that you can reach your opponent sooner. Note that there are Xel'Naga towers at the corners to whach out for your base (for like unit drops, or flying units)
it has mineral fields with 50 ore and vespene gaysers with 5000 gas
