About the Game

Step into the world of Shiltz with SealM on CROSS, a role-playing game that reimagines the classic MMO experience through a lens of vibrant cartoon visuals and nostalgia-driven design. Every monster you encounter has been crafted with its own personality and expressive appearance, bringing a sense of charm and life to a world that feels both familiar and refreshingly playful. Whether you are returning to a beloved era of online gaming or discovering it for the first time, SealM on CROSS offers an adventure that balances lighthearted aesthetics with genuinely engaging systems.

One of the first decisions you make in the game is choosing your class, and each option brings a meaningfully different experience to the journey ahead. The Priest offers supportive and altruistic gameplay, while the Knight brings discipline and defense to the front lines. The Warrior charges in with raw power, while the Mage commands mysterious elemental forces from a distance. For players who prefer agility and flair, the Jester delivers acrobatic combat, and the Hunter provides precise and nimble ranged play. Rounding out the roster is the Cook, a uniquely talented class that adds a creative dimension to the group dynamic. Each of these classes is not just a cosmetic choice; the game's dedicated combo system means that combat feels distinct and personal depending on who you play.

Outside of direct combat, SealM on CROSS is built around a rich set of companion and progression systems:

Pets: Select from a variety of companions that fight alongside you and add personality to your adventure.
Guarders: Mount these creatures to traverse the expansive fields of Shiltz with speed and style.
Couple System: Partner with another player to share your journey, gain unique benefits, and grow stronger as a pair.
Fishing System: Take a break from battle to cast your line and collect useful items in a more relaxed setting.
Seal Talk: A built-in social feature that makes it easy to meet other players, form friendships, and organize group activities.

For those who crave challenge and high-value rewards, the Field Boss Raid system puts powerful and visually distinctive bosses across the world map. Taking on these encounters requires coordination and preparation, and the payoff comes in the form of premium rewards that are worth the effort. These raid moments are some of the most exciting the game has to offer, particularly when tackled with a well-organized group.
