Hanya has gone missing, and your squad is being sent into a contaminated zone to bring her back. In M:Brace, you lead a team working for the Pnakotus Ark, an organization dealing with dangerous entities known as Anomalies. This sci-fi porn game combines collecting heroines, building combat teams, and uncovering their more intimate sides between missions.
You recruit characters through gacha summons, then choose a lineup of fighters with different abilities. Tanks help absorb damage, while Archers and Mages attack from a distance and Support characters keep their allies fighting. Level up your heroines, equip them with gear, and collect their shards to increase their stars. As your roster grows, you can try different combinations rather than relying on the same team for every challenge.
The campaign puts those teams through offensive and defensive battles. Some stages ask you to destroy the enemy base before the timer runs out, while others require you to protect your own. Your formation and choice of characters matter, especially when ranged defenders can reach enemies across towers. You can also bring up to two Goddesses, whose stat bonuses strengthen your squad. Allied skill use builds their energy, triggering a Goddess skill when the gauge fills.
Between campaign missions, take on timed bosses, climb Chrono Tower, or defend against waves of enemies. Wave defense lets you adjust your formation between attacks, but defeated characters cannot return for the rest of that attempt. For competition, enter the Arena or try Card Duel, a best-of-three mode where you choose cards before each round. Each round has a cost limit, so you need to decide which effects to use now and which cards to save for later.
Progress through M:Brace to unlock sex scenes and erotic story chapters featuring the women you meet. The military missions give way to private encounters with characters such as Hanya, Amy, and Eve, with unlocked chapters available to revisit in the Album. The hentai content also extends into character-focused Live Streaming Events, which have their own affection progression and CG rewards.
During these events, send gifts to the featured heroine to earn affection points and unlock more of her content. Upgrade the Fans Club to improve your event token production, then spend those tokens on gifts and toy interactions. At the highest affection level, using toys builds a climax gauge that triggers a CG sequence when full. Keep earning points to unlock additional XXX rewards and chapters for your Album.
Build your squad in M:Brace, head out after Hanya, and get to know the women fighting alongside you when the mission is over.
