Gah!

Welcome, mortal!

I am Gah, custodian of Purgatory.

I have been tasked with preparing a series of challenges for you.

The stakes are high — the future of all humanity hangs in the balance.

You will fight your way through hordes of enemies from different times and worlds.

You will wield melee weapons, ranged weapons, magical arms, and even firearms.

In each challenge you will improve your skills.

If you fail, you will try again.

I have prepared a small village where you can upgrade your abilities and increase your chances of survival.

After every victory you will receive a reward.

Let us waste no more time — the fate of humanity rests in your hands!
