Here are two cool features from Starcraft 2…

1) There are these cool structures called Xel Naga towers spread out across the maps…. they look like some kind of portal thing, but what they do is allow you to have a larger range of vision around that tower if you have a unit standing next to it.

2) You can now “hotkey” as many units as you want into one sub-group on the number pad. That’s right, you can select more than 12 units and assign more than 12 units to a hotkey. I had 41 mutalisks hotkeyed to #1 earlier and it was pretty awesome.
