Yes, actual end game has one big complex uber if one can say that. First you gather 3 keys (1 from nithlakh/act3 sewers, act2 "duncraig" uber and 4 act boss dolls). Then you use those keys in act 5 to open desert area uber - multiple mini bosses there. They drop charms and 3 dolls + doll from act 5 dragons mini map - you open chaos church. In there you walk long walk and find entrance to old tristram map. That is end game uber map there. Kill bosses to get charms and uber runes?
Sad part about this mod now is - server. Gathered all three keys, opened uber - poof server went kebeni materi. All games gone, no keys left. Repeat ? Probably....
