Sacrifice by Sword

Lore

All time and purpose has ended, as you're stuck in an eternal swordfight to the death against the followers of various gods. Your god demands sacrifices in his honor, and promises to bestow you with ever-increasing power the more you sacrifice. But beware, such a promise has been given to all who suffer in this realm. Will you rise above the rest, or will you be destroyed by them? One way or the other, there is no salvation.

Controls

Description

Basically, the game is a never-ending team deathmatch. The stakes are constantly escalating, as new people are being poured into the world. Each carries a soul, and the killer of each gets all those souls (even the used ones), meaning the amount of souls ever only goes up. The AI also knows how to purchase upgrades for themselves, so there's a possibility you will eventually face someone much exceeding your own level of strength.
The game is played on a 1km² map, and there are also some unarmed characters serving as easy pray.

Spectator Mode

If you get tired of that, you can go enjoy Spectator Mode, which is the same game, but you can fly around and see how everyone is squabbling. It's a lot of fun, and if you leave it running for long enough, you might just see some characters emerging as superior fighters, and thus the populations of those gods increasing.
