Slide through danger
Carry speed through the battlefield and turn narrow gaps into escape routes.
A third-person survivors roguelite.
Slide, leap, and unleash elemental chaos. Turn simple weapons into run-defining evolutions, gamble for power at Mutation Altars, and carry your build through the Forest, Glacier, and Dominion.
Automatic attacks. Active movement.
Enemies constantly close in while timed formations add larger bursts of pressure. Your weapons attack automatically; you decide how to move through the crowd, when to slide, and what to leap over.
Kill elites, open chests, collect items and runes, and decide when to gamble at Mutation Altars. Defeat the boss and take the build you made into the next area.
Carry speed through the battlefield and turn narrow gaps into escape routes.
Jump over bodies and hazards instead of waiting for the crowd to make room.
Your position changes where attacks land, what they hit, and how returning weapons travel.

Weapon evolutions
Evolutions do more than raise the numbers. They change the shape, timing, movement, or target rules of the attack.

Send an enormous sun through the crowd.

Turn a piercing shot into a field of falling spears.

Call a lightning spirit into the fight.

Crush enemies between colossal stone hands.

Move to guide the blades through enemies again.
Items and runes
Weapons define your attacks. Runes tune their behavior. Stackable items push damage, movement, defense, economy, and the rest of the build.



The mutation altar
Offer one of your weapons to the altar and take the first reward. Then make the real choice: walk away with what you gained, or push your luck for another slam as the corruption climbs.
Take your build into the next fight
Battle through the Forest and Glacier, defeat their bosses, and unlock the route to the Dominion. Your build survives the journey, while Bound Essence earned across runs opens more possibilities for the next attempt.

Open ground, dense crowds, and the first test of a new build.

Frozen terrain, harder enemies, and a different kind of pressure.
An elemental arena of anchors, beams, and a boss that makes you use the whole build.
Let chat have a say
Conclave lets Twitch viewers vote on challenges and gifts during a run. Chat can help, make an upcoming fight more dangerous, or change the risk around a Mutation Altar.
It is optional and off by default. Play HordeSlam normally, or invite the audience in while keeping control of your movement and build choices.
No Twitch connection is needed for normal play.
Chat chooses between bounded challenges and gifts.
You still control the survivor and every build decision.
