Map 800 is the Christmas event map for 2011 and 2017 onwards. In this map every mouse is a shaman. You cannot receive any event items or titles from this map, unlike most of the event maps added. After playing the map, points on the leaderboard are not reset, unlike other maps with shamans.
Shaman skills are disabled in this map. However, the shaman difficulty modes still apply.
The shaman color code is #00FFFF.
In Christmas 2011, every mouse playing this map wore an outfit with items
. Since Christmas 2017, the outfit changed to only wearing a Santa hat
.
Strategy
Fight with the other mice to be the last one alive, then simply go to the cheese and go back to the hole. This map is similar to Survivor as the shaman tries to kill all the other mice. However, unlike Survivor, you are not the only shaman and your cannons are not at the top of your item box, so be ready to start summoning before someone else cannons you to your death!
Since everyone spawns at the same location, you should move to a safe place at the start of the map to avoid the first wave of cannonballs usually aimed at the inactive mice. In this map, you can use portals, so you could use those to stay alive or attack. Note that all shamans use the same set of portals, so the portals may be moved to different positions by other shamans.
Only the last shaman standing will be able to enter the hole, hence there is no need to rush for the cheese. Since everyone is a shaman, they will earn experience points for "saving" the shaman that entered the hole.
