I made this race map on Blackout and I must say it is good. Here's the link to the video on the map: http://ie.youtube.com/watch?v=8JlMr1FLkNg and the link to the map: http://www.bungie.net/forums/posts.aspx?h3fileid=38472598
well. you didnt do that much other than add a few barriers for the track. no originality, but it doesnt look horrible. 2/5
The Destination is not placed properly for a race map, put a Tele in it so people can't walk into it and put a grav lift on a weapon holder so people can't stay idle in it to get points.
the video helps, but u need pics, read this thred to kno how to get pics http://www.forgehub.com/forum/showthread.php?t=1196
