open Outcast is a total conversion mod for Crysis Wars that should become an unofficial successor of the Action-Adventure Outcast (by Appeal).
Oasis is the first playable technology preview of the open Outcast project which aims to create a free successor of the Action-Adventure Outcast (by Appeal). The story/level of this mod isn't directly connected with open Outcast (though everyone who played the original Outcast will see that everything was designed in it's style). Moreover Oasis should demonstrate what is possible using standard Flow Graphs - the next step will be adding custom Flow Graphs and bigger modifications to the sourcecode. The whole gamemedia is custom made and you already can solve some quests which feature dialogues and voice acting.
