Still, i like the Halo 2 Wraith better than Halo of course... but the H2 Scorpion really is nice! I love it, and killing the driver too! But the wraith could have been changed to...

Primary Fire: 1 shot Kill (100% - 200% Health)
Secondary: None
Boost: Ctrl + W, A , S, D

and the some nice animations like this would have been added:
Hijacking slow vehicles
Climbing onto a Tank or Wraith and then Planting a 'nade inside!

But still, CMT is great, and i really liked the maps, especially CMT_Coag and all those CMT styled weapons. CMT ROCKS!
