This is how I do it.
Start ep2 game
Go to temple. It has 2 maps.
If the first room after the warp room is open to the sky, clear it and the next room.
If it is not, go north into the hallway, kill 2 rappies, then back. Go east into room with tower in center kill 2 rappies, then go north and kill 3 rappies.
Return to pioneer2 and start government quest 5-1(?). It should have the same map as 2 did, clear those same rooms and lobby.
