Distinctive Elements:
Join the Valentine Event for Exclusive Rewards
Take part in Project QT's ongoing Valentine event and enjoy exciting activities where in-game characters gift you chocolates. Interact with these characters to deepen your bonds, uncover their personal stories, and grow closer. Plus, simply logging in during the event grants you special rewards that are sure to delight.
Engage and Overcome Your Foes
As you start each level in Project QT, you'll encounter enemies and enter battle. Assess the attributes of your team and opponents to strategically pick matching elements, aiming to collect as many as you can. Watch the move counter on the left side of the screen, which shows how many matching moves you have left. Your whole team attacks once all moves are used.
A core part of Project QT's gameplay is maximizing your collection of matching elements within the limited moves. Players often use boosters similar to those in match-three games, deploying them strategically to clear multiple elements at once. These boosters have different effects, from wiping out large board sections to setting off chain reactions. To handle different enemies, you'll need to keep adjusting your team lineup.

Battle Cosmic Viruses
In Project QT, you play a key role in defending humanity from cosmic viruses bent on causing chaos. The story reveals that a scientific experiment accidentally opened a black hole, allowing mysterious viral creatures from space to enter our world. Partnering with resilient heroines, you must stop these invaders and restore peace—a conflict you can't ignore.
Project QT's gameplay is straightforward, letting you launch attacks and plan strategies easily. Each level screen is split into areas showing enemies and a grid of matching elements. Connect these elements strategically to power up your characters' attacks, requiring careful tactical thinking to win.
Build a Powerful Team to Face Enemies
A standout feature in Project QT is its attribute counter system, crucial to battle success. Characters have four attributes: water, fire, wind, and lightning. Each attribute deals 50% extra damage to its opposing weakness. This strategic edge lets skilled players quickly defeat vulnerable foes by leveraging their team's strength.
Beyond clearing levels, you can also enter PvP battles against other strong players. This competitive arena tests your squad's mettle. Continuously summon and enhance powerful characters through upgrades and evolution to overcome varied opponents. With a wide selection of characters available, adapting your squad's approach lets you build increasingly effective battle formations.
