Well, like writen in the title. I have some problem to got the yellow and red Ressources, in multiplayer game, with the sentinels race. I show you the plan that i do habitually :

First : I Build my base (with my first blue ressources spot), then I build Drone Troopers, for help my defense. To that, no problem.
Second : I build two others base (one with the nutrinium ore and the others with plutonium), and I build skimmers, stalkers and enhancement pod. Then I Attack, and kill everybody in the map.

but, i only take low, in the setting of the players, when i start the skirmish. But, when i take medium or high (when you have the yellow and red ressources on the map.), i'm already dead, because, i cannot support the construction of defense and of the building for others ressources spot, simply because, the cost is too high. I can't build an army, when i have to construct the scuttlers for the construction and for the harvest, when i have to convert my upgrade my upgrade modul, into defense, supply, stockage and repair building. Adding to that, i have to construct in the same time, all this structure, in differents place of the map AND an army.

If you got a tactics, for take one yellow and one red spot of ressources, please, help me.

Note : Habitually, i take 2 scuttlers, for the blue, the yellow and the red ressources, and 1 for the green one.
