General information

 * To win, be the last team standing.
 * Should an allied hero die, your team can revive you. This takes only a few seconds.
 * If an enemy dies, but their team remain alive, you can deny the enemy's revival by using their gravestone. This takes 20 seconds.
 * The contents of the map are randomly generated each time you play, so while the rooms physically remain the same, the paths between and their contents will shift between games.
 * Roshan destroys a ring of rooms every five minutes, starting with the easier outer ring. Players in destroyed rooms take very high damage per second.
 * Randomly, a large Cheese will spawn in a chest, and all players will be notified. The first player to pick up the cheese claims a large bounty of Battle Points.

Heroes
Players can pick from most of the heroes available in Dota. Their abilities remain unchanged from the base game of Dota. Heroes start at Level 1, and have an, , and two s.

Caps and bonuses

 * Players can only earn a maximum amount of Battle Pass points per week. This cap can be increased by leveling the Battle Pass.

Emoticons

 * Emoticons are rewarded for winning matches.

Strategy

 * Dynamite can be used to destroy the otherwise impassable stone walls, or it can be sold for 800g, or it can be used as a 1000-damage nuke to an enemy team (with the proper setup, to ensure that it damages them). Be careful though, as placed dynamite will damage everyone in the radius, including yourself and your team.
 * Always open chests before going shopping. Often, whole assembled items will drop from chests, which may change your purchasing choices. Alternatively, you can sell the items you receive from those chests for gold.
 * Observer Wards can be placed on the other side of gates and stone walls to scout ahead.
 * Some heroes are better at clearing creeps, some are better at clearing "boss" units, and some are better at fighting enemy heroes. Try to find a good balance between these so that your team is not too weak in one area.
 * Some of the map is on higher elevation than others. Always try and fight enemy ranged heroes while you have the high ground.
 * Enemy corpses will always drop their items and current gold. Invest this gold into items to help you gain a lot of power quickly.
 * Always stay on the move. The timer is ticking and Roshan is moving inwards. Be careful not to get caught in a room he controls!

Trivia

 * The Underhollow is a battle royal with cheese, referencing the famous Royale with cheese scene from Pulp Fiction.
 * The room "Knights of Ostarion"'s description text is in all caps. This is a reference to CAPS LOCK LEORIC, an infamous item build from the DotA Allstars days.
 * The model in the "Lord of Oblivion" room is wearing the Golden Nether Lord's Regalia Set. This set was distributed to only 25 players worldwide, making it one of the rarest cosmetics in the game.
