About this game

A dimensional rift has opened.
Stop the endless waves of hostile entities and defend a world on the verge of collapse!

**Defense Service** is a special response agency created to protect humanity from dimensional disasters.

Mysterious rifts are appearing across the world, releasing dangerous unidentified entities.
Your mission is to eliminate the threats, secure the area, and stabilize collapsing dimensions before it is too late.

And today,
you have been assigned as the newest agent on the front line.

🌀 **Hold Back Endless Waves of Enemies**

Deploy to active rift zones and stop the relentless enemy assault.

Your top priority is simple: prevent enemies from breaking through the defense line and survive the operation.

Easy to play with one hand, but as the battle intensifies, quick decisions and smart choices become the key to victory.

🃏 **Choose Your Build in Every Battle**

Defeat enemies and gain combat experience to unlock new upgrade choices.

Decide which abilities to strengthen,
which combat effects to add,
and how to shape your build during each run.

Even on the same stage, different choices can lead to completely different battle strategies.

⚔️ **Build Your Own Combat Setup**

One powerful ability alone will not win every battle.

Combine equipment, runes, summons, and other growth systems to create a setup that fits the situation.

The more you fight, the more your own strategy and progression style will take shape.

⚡ **Keep Growing After the Battle**

Use the resources collected in the field to upgrade your equipment,
strengthen your runes and summons,
and increase your overall combat power.

Unlock new growth systems and prepare yourself for more dangerous rifts and stronger enemies.

🎯 **Challenge Higher Stages**

Clear Normal Stages and take on more difficult battles.

Do not settle for simply clearing a stage.
Aim for better results, stronger rewards, and new challenges that put your upgraded combat power to the test.

The stronger you become, the greater the missions ahead.

⏱️ **Earn Rewards Even While Offline**

Operations on the front line never stop.

Even when you are away,
Rift Management and ongoing assignments continue generating resources for your next mission.

Return, collect your accumulated rewards,
and prepare for the next battle.

📋 **The Mission of Defense Service Never Ends**

Eliminate dangerous entities.
Contain dimensional rifts.
Secure combat resources.
Strengthen your equipment and forces.
Advance into increasingly dangerous operation zones.

As long as dimensional collapse continues,
the mission of Defense Service will never end.

**Join humanity’s last line of defense.
Become a Defense Service agent and face the dimensional rifts today!**
Defend humanity and stop the rift invasion!
