For the act about this gate, see The Infernal Gate.

The Infernal Gate

The Infernal Gate is a special portal that transports the player character to the Pandemonium Fortress.

The portal is orange and energy resembling terrible silver-black viscous liquid runs along its surface, forming patterns of tortured faces while tendrils of energy rage along the outline of the portal. Its most striking feature, however, is the tortured screams of numerous humans: men, women, children alike, emanating from the portal, forming a terrible mixture of ominous sounds.



The Infernal Gate in the cinematic.

The Infernal Gate was opened by the combined efforts of the Prime Evils after they reunited once again. Diablo passed through it into the Burning Hells.

The portal's creation was witnessed by Marius after he was charged with the duty of destroying Baal's Soulstone by going to the Hellforge. It was here that he witnessed the Dark Wanderer's transformation into the physical manifestation of Diablo. This drove him insane and led to the events leading up to the expansion.

The portal was created so that Diablo, the Lord of Terror could go to the Burning Hells and rally the demonic forces for the invasion of Sanctuary, while Baal retrieved his Soulstone to capture the Worldstone which was the only thing preventing the Burning Hells from spilling into Sanctuary. Mephisto decided to watch over the portal while his brothers accomplished their missions.


In Diablo II, players must enter the Infernal Gate after they have defeated Mephisto in order to gain access to Act IV to hunt down and destroy Diablo himself.

When players enter the Durance of Hate Level 3, they can already see a glimpse of the Gate when they stand on the edge of the pool of blood. However, they can not enter it until Mephisto is defeated. When Mephisto is defeated, the portal will start 'coming to life' and a bridge of bones and skulls will rise from the blood-pool, creating a passage for the player.


After Mephisto is defeated, the portal 'comes to life' and can be entered.

Entering the Gate starts the new act after the cinematic. The player finds him/herself in the Pandemonium Fortress, a major plot hole considering this is the same portal that Diablo entered, and he cannot have ended up in the Fortress but in his Lair. Short of using waypoints, this gate is the only way to reach Act IV from another Act.

It is notable that during the above mentioned cinematic, Mephisto chants exactly the same words found in the Introduction section of the Diablo instruction manual.
