I have just played Odis. I like getting back to SOG. A couple of observations.
1. When you first start, you have to have 10 points in order to HALO.
2. When you are shot, you cannot respawn in place. You have to respawn at a base.
3. I find no way to call in CAS.
4. When you respawn at base, you are on the roof.

Just a few thoughts.
