There are three maps The Gym which plays with Grifball, RGrifball which plays with RGrifball, and Shattered which plays with Spacebound Grifball. Sorry for no screens but I made a video of all the three maps. Watch in 1080p! [YouTube - Kill Ball Map Pack Reviews About the Map: "Why did you end the game?, I liked it" "That was a good map where can I download it?" "Where can I get those maps?" "I give it a 4 out of 5" Enojy!
First You set up an incline. Then you place a killball on the incline while it is on phased mode then without holding the killball change it to normal then shoot it with any weapon.
When I saw the maps on the video I thought that they were going to be terrible, but when I downloaded them they were actually pretty good. Nice job!
