Just till I get the full write up posted, try going for 8VPs instead of 7.
Also, a note on objectives.
Imagine the board is divided into 5 zones. Each player has a deployment zone, and there is a central band into which half the items are deployed. This leaves a strip of no-man’s land on each side, between the central band and the deployment zones.
Set up the Objectives with one in the middle area where the items go, and each player setting up one of the remaining objectives in the strip of no-man’s land on the opposing side of the middle band. If you see what I mean.
If a model leaves the table via Infiltrate they cannot return. If they leave via Scour then they can come back onto the cube they left the board from.
