Sacred tree is a fun blood style scenario. For those of you who dont know, a blood is a scenario with auto-spawning units, a good example is Norse Wars. You fight an epic battle for control of Sacred Tree in the center of the map. Controlling it has many benifits such as spawning dyrads, with extra crush damage to take down those mighty walls. There are 12 heros you progress through as you kill more units. You may buy resources to advance and do upgrades, and make myth units, who are specially modified to be good against the heros. Also includes shapeshifting units who can be moved around an turned into towers at strategic locations. All sorts of extra goodies such as building kills, everything you could ask for in a classic, original blood, one of the first for AOT.
