The Twisted Treeline map was reworked, and the new version released with patch V220.127.116.11 on October 17, 2012.  It was previously located near Zaun, but was retroactively relocated to the Shadow Isles.
The location known as the Twisted Treeline is located in the mysterious Shadow Isles. An eternally thick, unnatural fog blankets the islands from the view of outsiders. It is thought that the islands are home to countless forms of undead, though no one seems eager to perform the exploration necessary to find out the truth.
The Twisted Treeline is a two lanes map where two teams consisting of three players battle in fast-paced action while their ultimate goal is to destroy the enemy team's nexus. Aside from its two, slightly curved lanes, the map also features several neutral monster camps and two altars to be captured as well as a free health pick-up - all situated in the jungle between the lanes - giving plenty of opportunities for team fights. There is also a path over the top lane which leads to lair. The team who defeats the horrific creature inside receive the Crest of Crushing Wrath, which provides a spooky buff: champions become ghosted, ignoring all unit collision for the duration of the buff. Additionally, nearby minions gain aura bonuses, and briefly terrorize nearby enemy minions on first contact.
Deep in Shadow Isles lies a ruined city shattered by magical disaster. Those who venture inside the ruins and wander through the Twisted Treeline seldom return, but those who do, tell tales of horrific creatures and the vengeful dead.
- Two lanes to fight your way to the enemy base.
- A jungle populated by neutral monsters of varying degrees of toughness.
- Powerful turrets defend key areas on the map. You must confront these in addition to your enemies if you are to make headway toward victory.
- Two bases at opposite sides of the map, populated by a shop, a nexus and one turret to defend the nexus.
- A Ghost Relic is located in the middle of the map.
- Two altars situated on both sides of the jungle. An altar is sealed for 90 seconds after capturing it.
- New items to complement its fast-paced gameplay, and 850 base starting gold.
- Work with your teammates to use the close lanes as a chance to kill enemy Champions as a team.
- The basic strategy is to have 1 player in both lanes, and a jungler in between.
- The next level of strategy is to funnel both jungle and top wave resources into a single attack speed scaling champion.
- Because of the "middle" lane, champions with the ability to hop the wall or roam effectively are very powerful.
- The jungle in Twisted Treeline is easier to clear compared to the Summoner's Rift jungle.
- The jungle area in Twisted Treeline is good not only to sneak on the opponent but also to outsmart them by running away or baiting them into a bad position.
- AD carries are viable on Twisted Treeline, but they must be protected by team like on Summoner's Rift. Roles of champions are more or less the same as in 5v5, but a setup with an AD carry should have enough cc to make him/her safe.
- A critical area is the lair of , located at the top of the map. It is a high value objective, so pay close attention to the location of enemy champions so that you are aware when they attempt to take him down. Keep in mind that the revised Twisted Treeline's shop does not carry wards, so vigilance is your only means of protecting the spider from the other team.
- Although wards do not exist in the shop, some champions like , , , , , , and have abilities that can be effectively used as wards.

Interview about the map
So in regards to the new map, which is one of the hottest items that we're really excited about, we're about to roll one out. It's going to be going into the beta shortly. I don't know if it's in this release or if it's in the release at the end of the month. It's coming out really soon, it's a two lane map, it's awesome, there's a lot of action, it's really well designed to force action to the middle of the map, and it's designed for a 3 on 3 play experience. So it's very different experience, it will be a lot of fun for users to go bang away on that.
The map was first shown to the public on October 19, 2009 on the games' Facebook page.
