I'm now working hard on the single player menu interface. The UT progression works and also has trophies that appears by maps you have completed in the interface. This should also be able to unlock novelty features (for offline play, similar to the Rare/Fradical games). Unlockable characters are not possible yet, but would be hard to implement considering the whole mod compatibility thing, since mods wouldn't have access to the same features baseoa would have and would spoil all of the surprises.
No results screens yet, but you can be sure there will be a form of "YOU'RE WINNER !!" in there somewhere. Even at the incomplete state, it's already a more compelling single player than both Q3A and Q3TA and in some degree their console ports.

This is important because OA3 is based on the Missionpack interface code, which does not even provide the same single player q3_ui (classic) interface did which meant no unlockable tiers etc. Addressing this problem as early as I can helps.
