Being able to walk on your walls would be AWESOME! Another cool thing would be if you were able to set up patrol guards. A simple bot that walks back and forth on a path that you set and when an enemy comes within his sight he can walk to it and kill it!
This game is nothing new from ALL of R2's games. They need to branch out. They have so many games with the same ideas. They aren't trying to be innovative and with all of the gaming competition out there now you need to make unique games.
Thanks for the info!
