after clear out all unit in the upper zone in the map,i still cant pass the level

Yeah me too. I can clear out all the units from the top sector with plenty of time to spare but can't seem to finish the level. I've had 9 recon units sweeping the area for enemies but can't find any. I've even killed all units I could find on the entire map and still no luck. Anyone else have this problem?

wonder why no technical staff reply to the topic

of course we could report the problem as suggested, but then what's the point of having a technical forum if you're not open to discussing technical issues.

Not 100% sure on this but the Tech Help section is for technical problems running the game not game mechanics per se. Focus is pretty darn good at helping with driver and crash issues but I don't think I've seen them reply to posts here about the game itself.

I suggest starting a thread in General and state the problem as clearly as possible and I am sure somebody will reply.
