Keith,
I'm not sure if this should be considered a bug or a balance issue, so hopefully you can take a look at the attached save and figure out why this is occurring.
In the opening moments of this game, I spawned on Ceasar with Eyebots to try for an alternate attack path at the Peacemaker. However, you'll notice I've dropped a picket on Broken Ridge. This is where the concern is; I've got a massive threatball growing from Special Forces units before the first wave even fires up. Let it run for an additional 3-4 minutes and you'll see just what all those Mini-Rams can do.
Now, I have to assume I'm on a Spec Force highway of some kind but this seems a little much for the opening salvo. Do I just consider this an unlucky spawn and move on or do you (or others, of course) see a way of balancing this off a tad? I'm going to goof around with it and see if I can't defend from it, but it's probably a dead seed.
