How AI is used

Some music, sound effects, and UI icons in Riftslayer were created with the assistance of generative AI tools during development. All AI-assisted content was reviewed and selected by the developer before being included in the game. Before the full release, all AI-assisted assets will be replaced with original music, sound effects, and UI icons created by human artists.

The developer's own words, from Steam.

About Riftslayer

Enter the Rift. Slay the hordes. Break the build.

Riftslayer is a fast-paced 3D action roguelite built around one simple idea:

Start weak. Build something ridiculous. Survive the chaos... if you can.

Fight through massive waves of enemies, collect experience, choose upgrades, and turn a simple character into an increasingly destructive build.

More projectiles. Faster attacks. Bigger areas. Shorter cooldowns. Stronger effects.

Every upgrade pushes the run further toward complete chaos.

Build Something Overpowered

Combine weapons, abilities, and perks to create powerful synergies.

A build that starts with a few basic attacks can quickly evolve into a screen-filling machine of projectiles, explosions, area effects, and rapid-fire abilities.

There is no single correct build.

Experiment, stack effects, and find combinations that completely change how your run plays.

Fight Massive Hordes

The longer you survive, the more pressure the game throws at you.

Enemy numbers increase. Elites join the fight. Bosses force you to reposition. Attacks begin filling the battlefield.

Keep moving, keep upgrading, and try to stay ahead of the escalation.

Keep the Combo Alive

Kill enemies quickly to build your combo and push it higher and higher.

Maintaining a massive combo means staying aggressive and continuously finding new targets.

Lose momentum and the streak ends.

How far can you push it?

Push Deeper Into the Rift

The Rift is designed for players who want to keep pushing beyond a normal run.

Difficulty continues to increase as enemies become more dangerous and the pressure keeps rising.

Go deeper, chase better results, and find out where your build finally breaks.

Death Does Not Always Mean the End

Some runs can continue beyond defeat.

Accept a Curse and keep fighting under increasingly dangerous conditions in exchange for the chance to push your score even further.

Sometimes surviving longer means making the run worse on purpose.

Progress Beyond a Single Run

Your progress does not end when the run does.

Unlock new options, improve your long-term progression, increase your Prestige, and return stronger with more ways to build your next character.

Face Bosses and Elite Enemies

Regular hordes are only part of the threat.

Powerful elites and bosses break up the battlefield and force you to adapt your movement and build instead of simply standing still and watching enemies disappear.

Chase Better Runs

Riftslayer is built around replayability.

Try different builds.

Push higher combos.

Reach deeper Rift levels.

Improve your score.

Find stronger synergies.

Then start again and see how much further you can push the next run.
