Hub 2: Sacred Grove

Sacred Grove is the secret map from the second hub of Hexen, Shadow Wood. It is accessible via a second portal on the Shadow Wood map, which is unlocked once the puzzle has been solved.

Strategy
The strategy is very simple. Kill the ettins as fast as possible, otherwise new ones will keep appearing.

After a while, if you don't defeat all of the ettins, they additional ettins will teleport into the area. If they become too numerous, a message saying something like "you’ve waited for too long, now you die" will show and instead of ettins, chaos serpents will start appearing in a never ending cycle. You will never be able to kill them all to reveal the switch, and the exit will be blocked off.

Walkthrough
This is a small, roughly circular map with a single post in the centre. Once you've killed the Ettins, a handful of powerups will spawn and steps will lower downwards towards the post in the centre, revealing a switch. This switch gives the message "a door opened on the Forsaken Outpost", which is a map from Hub 4. The switch opens a door making the secret map (Desolate Garden) of that episode available, and it cannot be reached in any other way if this switch is not found.
