Glad I could get you started in the right direction! I think as long as a small portion of the unit is on screen, pathfinding might work, so spawning them with like a 10 pixel overhang on will give a good impression of marching in to the scene. You can also play around wiith the solids behavior to make walls around the camera zone, but have the layout extend past the camera. If your enemies pass through it, that might work. Unfortunately I don't have C2 in front of me, so I can't test either answer. Let me know if either works, and if not, I'll help brainstorm some other options.
