Creating a two-world MMORPG in UEFN with Fort Knight Legend 2

Massive worlds, cooperative boss battles, deep character progression, and over 100 unique skills—Fort Knight Legend 2 sets out to deliver a true MMORPG experience inside Fortnite.

Created by Love-is-Real Games, the game spans two expansive worlds where players can battle powerful bosses, explore dungeons, collect gear, and customize their playstyle through a wide range of equipment and abilities.

Alongside PvE adventures, players can also dive into PvP combat and progression systems including fishing, alchemy, equipment reforging, and skill fusion. Here’s a closer look at the technology powering the experience.

Building a better loot system with Scene Graph

The team’s original vision centered on a classic MMORPG gameplay loop: defeat monsters, collect increasingly powerful gear, and experiment with different combat builds.

In their previous project, dynamic gameplay objects were built primarily with props. While effective, this approach introduced limitations in both scale and development efficiency.

“For this sequel, we fully leveraged Scene Graph to build dynamic objects such as combat loot drops,” explains the team. “This upgrade has not only drastically boosted our development efficiency but also delivered significant optimizations to in-game runtime performance, completely breaking past limitations and allowing players to fully immerse themselves in the thrill of looting and gearing amid fast-paced, intense combat.”

Creating flexible combat with Verse

Combat sits at the heart of every MMORPG, and the team wanted players to have meaningful choices in how they approached battles.

“To this end, we developed a Gameplay Ability System (GAS)-like combat framework based on Verse, and created all in-game animations and visual effects directly within the editor using Sequencer,” says the team.

Combined with animations and visual effects created directly inside UEFN using Sequencer, the system supports more than 100 unique skills and buffs. Players can freely combine classes, abilities, and equipment to create distinct combat styles, encouraging experimentation and strategic team composition.

Expanding gameplay through improved UI

As communication between Verse and Unreal Motion Graphics (UMG) has become more seamless, the team significantly streamlined their UI development pipeline.

“In this sequel, we have not only fully revamped the visual polish of the HUD and all system UIs, but also added a host of new gameplay systems including fishing, alchemy, equipment reforge and skill fusion,” explains the team.

These additions deepen progression beyond combat, giving players more ways to customize their characters and engage with the game’s world.
