We know that the altar (top left), 2 central towers, and bottom-right village will be the primary objectives.
A few thoughts- with so many objectives, I think we concentrate on a bundle of them that we can secure- instead of trying to hold everything on the board.
So when I look at the easiest objectives to ignore- it would have to be either the altar top left or the village far right. The two central towers are near the only Chaos specific objective that is land-based- the bridge. So we need to secure the towers, squash the Empire near the bridge, and take it too. Since the river is in our way, this will likely be a two-pronged attack with one force on each side of the river.
So that leaves a third force we could create- does it hold the altar or push to the village? The simplest answer is to hold the altar because it is on our side. But because we are Chaos, I think we could hold it simply by destroying every Empire unit on that side of the river as we push to the bridge.
So my recommendation is:
--Our center army rolls towards the towers and the bridge, with the bulk of the main force on the east side of the river to hold off the Empire coming from the east
--Our heavy hitting shock troops start in the west, swoop around the left flank, destroying all Empire units as it pushes east to the bridge.
--We put token forces in the far east just to harass, protect the flank of the main force, etc.
--My Vanguard can be spread out anywhere, depending on where you need speed, diverting or Warmachine hunting
--I think killing the Empire General is probably doable
--I think destroying all the Steam Tanks would be a bonus, but is going to be difficult, and shouldn't distract us from completing our other missions
