Slayer Tycoon (v.)

Slayer Tycoon is a 2-player combat tycoon game on Roblox created by Coldjason, inspired by the Demon Slayer: Kimetsu no Yaiba anime. Players choose between the Slayer or Demon faction, build and manage a tycoon base, and fight directly against their opponent in session-based matches. With 219M+ visits since March 2021 it is a long-standing hit in the tycoon genre, currently running version 2.0 - the 2026 anniversary update.

The session-based design is a defining feature: the game explicitly does not save progress, making every match a fresh start. Players chop wood and mine ores with their Hatchet and Pickaxe tools to build their tycoon base, then unlock faction-specific combat abilities to take the fight to their opponent. Katana moves (E, R, T, Y, U), Roll dodge (Q), and ultimate abilities form the combat system:

• 🏠 Tycoon Building - gather resources to construct and upgrade your base, funding better abilities and equipment
• ⚔️ Slayer Abilities - Breathing Styles accessed through Katana combat; fire-breathing and other techniques for the hero faction
• ⚔️ Demon Abilities - Blood Demon Arts for the Demon faction, with Moon Art (700 R$) as the premium high-tier ability
• 💎 Clothes Merchant - an NPC spin system that awards cosmetic Haoris as badge-linked rewards across rarity tiers: R, SR, SSR, UR, and the limited EX
• 🗺️ Infinity Castle - a special Demon-realm combat zone accessible via the Easy Teleport pass or by finding the Biwa Demon NPC

The Haori cosmetic collection spans 18 tiers from basic [R] drops to the ultra-rare [SSR] Green Checkered Haori and the [EX] Anniversary Haori exclusive to the 2026 anniversary window. The OG Player badge (2021 launch) and v2.0 Player badge (March 2026) bracket five years of the game's history.

Slayer Tycoon is well-documented by the Fandom wiki at slayer-tycoon.fandom.com (353 pages), making it one of the better-resourced games in the Demon Slayer Roblox genre.
