Fusionist is a turn-based strategy sci-fi game. Players lead a team of five mechs, strategically combining cores and mechs to create unique tactical combinations for battle. The game features three elemental types—Frozen (Ice), Burn (Fire), and Electric (Lightning)—allowing players to trigger diverse elemental reactions, such as ice-based control, continuous fire damage, and electric chain explosions, greatly enhancing combat strategy.

Each of the five mech classes has distinct roles: melee Striker, shielded Defender, ranged Buster, precision Sniper, and backline Support. Players can adapt their tactics to the battlefield situation. Turn-based combat emphasizes action order and formation placement, offering deep strategic gameplay.

Players can complete missions to collect resources, forge and upgrade their own mech squad. In the arena, they can compete with commanders worldwide, where team composition and skillful operation determine victory.

The new version introduces more powerful weapons and innovative core mechanics, allowing players to fully enjoy the strategic sci-fi mech experience.
