Nexus said on the 6th that it began a closed beta test (CBT) for its first standalone publishing (distribution) title, Frost Kingdom.

Frost Kingdom is a strategy simulation game set in the Middle Ages, touting itself as the world's first web3 social strategy game (SLG) that combines an SLG framework with a merge system that upgrades items by combining identical ones.

The CBT, running from the 4th to the 10th of this month, aims to collect data for a multi‑token tokenomics economic system and verify economic balance. Users can join the test by downloading the mobile app from the preregistration page or by accessing it on PC.

The CBT applies a payment system identical to the live environment. By applying the Cross Game Hub web shop platform developed by Nexus for the first time, it introduces an AI‑based web shop along with payment infrastructure.

Amounts spent by participants during the test period will be fully refunded as Red Diamonds, an in‑game currency, after the official launch. The goal is to gather economic data in a real payment environment while minimizing the burden on participants.

Jang Hyun-kuk, CEO of Nexus, said, "SLG is the genre that best fits game tokenomics, with a complex economic structure that connects resource production, exchange, and consumption," adding, "Through this CBT, we will raise Frost Kingdom's level of polish and use it as an opportunity to expand the genres succeeding on the Cross platform from MMORPGs to SLGs."
