Amazing Seasun Games announced on the 29th that it has rolled out a massive update to celebrate the 2.5th anniversary of its 3D subculture shooter RPG, Snowbreak: Containment Zone.

The highlight of this 2.5th anniversary update is the introduction of the 'Covenant' content. Covenant is a limited-time feature that unfolds new stories through a contract between characters and the Analyst. This system includes dedicated wedding skins, ceremonies, and stories, with Acacia and Marian added as the first Covenant characters. Both characters will experience new growth stories through the Covenant and have each received exclusive wedding skins.

Acacia, in particular, arrives with a dual-form skin as 'Acacia-Chrono Echo.' She features a new combat mechanism using flying blades; when specific skills are used during combat, her form shifts, changing both her combat performance and the flying blade modeling. Starting February 12th, 'Marian-Aquila' will be added as a limited character. Marian-Aquila is a skill supporter who summons heavy weaponry to perform coordinated fire attacks, providing buffs to specific allies and designed to synergize with Acacia-Chrono Echo. When using her support skill, she appears directly on the field to perform a coordinated attack.

A large number of new character skins have also been added. 'Echo of Bonds' for Acacia-Chrono Echo and 'Pure Feather' for Marian-Aquila have been revealed, along with 'Silk Embrace' for Cherno-Twin Dreams and 'Cloud Play' for Mauxir-Ghost. Acacia and Marian offer exclusive animations through a double-character Covenant interaction. Additionally, the dorm content has been expanded with a new 'Game Dimension' area and a dedicated 'Coin Tycoon' mini-game, and a feature has been applied to swap some characters to their 'girl' skin variants upon skin purchase.

Various benefits to commemorate the 2.5th anniversary have also been prepared. Through first and second-half attendance events, players can receive a chest to select one 'Harmony of Heart' event character, as well as 10-pull limited tickets for both characters and weapons. Additional 10-pull tickets, selection chests, and limited-time supply items will be provided sequentially through update commemorative mail and holiday mail. Notably, new users are offered up to 130 pulls. UI improvements and system optimizations have also been implemented, such as the ability to set skins or story spines as the main screen background.
