I love this game and have pretty much played it to death. I've noticed that the command towers don't really seem to give me a resource bonus though. I decided to test my theory on the map Standing Orders. There is a looping section of track in the middle of this map that you can place six towers in. If you put a command tower in the middle of this block of six and fill the rest with gun towers you can be sure anything they kill was within range of the command tower and you should get a very hefty resource bonus. I tried a few levels with the command tower upgraded to level 2 and a few levels without it. When I played without buying command tower I made sure I didnt earn any additional interest on the 600 credits saved by buying 6 gun turrets at the other end of the map, well away from the action. The resources earned from killing the aliens was the same with or without the tower but should have been 33% higher with it. Has anyone else noticed this or have I misunderstood how these towers work?
