About This Game

"Hellgate Reiko" is a deck-building zombie shooting defense game.

Reiko, a new hire at an android company, finds herself trapped at work after a hellgate suddenly appears during her overtime shift.
To escape, she must fight through monsters on each floor and close every hellgate she encounters...

A hellgate that can't be closed unless you XX!
Draw high-numbered cards to build powerful androids, upgrade your deck, and enhance your units to finally escape this cursed company!

Weapon Crafting

To create battle-ready, modified home androids, you must draw cards. The higher the number, the stronger the android you can build.

From machine guns and baseball bats to chainsaws, a wide variety of weapons are available.

Each weapon is ranked across six tiers based on the number you draw. Aim for the highest-tier weapons!

Card Upgrades

Defeat the enemies from hell to collect gold and purchase card packs, allowing you to obtain higher-numbered cards!

But beware… there are traps! Not every card you draw will be a good one. Test your luck!

Strategic Placement

Monsters are swarming from the Hellgate.

Freely position your androids to attack efficiently and fend them off!

And… Events!

If you successfully defend against the onslaught, various rewards await you.

Will you be able to survive in front of the Hellgate?
