Underworld is the multiplayer mode of Shadow Fight 2. It features online raid-style battles which allow players to team up together with other players to tackle the bosses. The bosses, called the Eternals, are powerful beings that have lived for thousands of years and they started to aim to destroy the world after the Gates of Shadows are opened. Playing Underworld is completely optional, players can enter it anytime after they defeat Dandy, Lynx's fifth bodyguard. After defeating Titan, Shadow ends up in the Underworld.

Username Edit

Players can enter the Underworld by tapping the Raid down icon on the bottom right of the map.

The first time a player enters the Underworld, they will be prompted to enter a username. Only Latin letters and numbers can be used, within a 3-10 character frame (no spaces). Once a player confirms their username, it cannot be changed.

Gameplay Edit

Each boss has a shield and the players must destroy it within a given time frame before they can finish the boss. After all the shield is destroyed, players can finish the boss in a final one-on-one battle. If they lose the final fight, they can repeat it until they win. Each raid fight consists of one round, lasting 45 seconds. Players can buy or obtain several items like charges of darkness and potions to aid them to deal additional damage or survive longer. There are certain things that make the raid fights differ from other fights:

  • The level and stats of all equipment does not affect raids.
  • No perks work in raids.
  • Underworld bosses are more aggressive than other enemies.
  • They are immune to the Stun enchantment.

Rewards Edit

Player will receive rewards at the end of a season, which last for three days. The rewards depend on the players' score and position at the League leader-board. The rewards are a supply of small and medium charges, raid keys, and a small amount of gems. Players at the 1st-5th place also have a chance to get a random item from the Monk's Set. The Monk items obtained this way will only be enchanted with tempest rage (no simple enchantment)

Dan Edit

Main article: Dan (SF2)

Dan is a level-like system. All players start with Dan 1. By accumulating enough score, they will receive a Dan promotion at the end of the season, along with additional rewards. Higher Dan allows players to fight bosses with Dan requirements. Currently, the highest Dan is 7.

Clan Edit

Main article: Clan (SF2)

Player can join a clan or create their own clan in Underworld. Being in clan will give player the advantages to fight bosses together with their clan members. It also provides a better chance to gather players during match-up.

Tips Edit

  • Using certain weapons may allow the player to perform better in raids.
  • Obtaining Ranged Weapon and Magic can increase the player's performance. Ranged weapon is unlocked after defeating Lynx, and Magic is unlocked after defeating Hermit.
  • Enchantments can increase the player's performance. Players can enchant their equipment with Shadow Orbs that can be won from eclipse mode, or they can use pre-enchanted equipment such as the Monk's set, demon weapons, special event weapons, and gem-purchased equipment.
  • Charges can help players in dealing damage.
  • Collecting the Monk's Set will unlock the Mythical enchantment Tempest Rage. Monk's Set and Tempest Rage can increase the player's performance greatly.

Trivia Edit

  • Soon after the launch of the multiplayer mode the strength of the bosses' shields was decreased. However the damage they dealt was instead increased.
  • All Eternals wield gem weapons.
  • If the two first players in a raid deal the exact same amount of damage, they will both get the first place reward at the end (if they win the raid).
