Whether ps4 works depends less on the hardware and more on which version the publisher chose to maintain.

Short answer

The feature is there on the platforms with an active build, and absent on the ones left on an older version.

  • Look for a cross-progression toggle in account settings before starting fresh.
  • Assume mobile versions are a different game with the same name.
  • Expect one number in every guide to be out of date; the method is what matters.

Siege rewards knowing the building more than knowing the gun, which is why map knowledge outranks aim here. Console certification adds weeks to every patch, which is why fixes land unevenly. Some features are disabled per-platform for reasons that have nothing to do with performance.

Crossplay versus cross-progression

The awkward part is rarely the step itself, it is knowing which step comes first. Handheld versions often trail the main build by a full season. A cut-down port is still a port, and the difference usually shows up in player counts rather than frame rates. None of this needs a paid tool, a third-party launcher or an account on a site you have never heard of.

Cloud streaming sidesteps the hardware question and introduces a latency one instead. Store pages list supported platforms accurately; trailers do not. It helps to understand why a step exists, because then you can adapt it when your situation is slightly different.

Which versions exist right now

Cross-progression carries your account; crossplay only puts you in the same lobby. Treat anything stated without a version number as provisional. There is usually a fast way and a reliable way, and it is worth knowing which one you are choosing.

  • Check the store page's supported-platforms box, not the trailer.
  • Check whether the version on sale is the current-gen one.
  • Region and platform change more than people expect, so confirm both.
  • Confirm whether your friends are on the same build, not just the same game.
  • Verify controller support separately from platform support.

How to check before you buy

The short version is near the top on purpose; the reasoning is there if you want to know why. Half the pages on this topic were written for a build that no longer exists, which is why they stop matching what you see. The developers have changed their mind about this at least once, which explains the older advice. Screenshots age faster than text, which is why this describes rather than shows.

Patch notes move numbers around constantly; the shape of the answer holds even when a specific value shifts. If a step reads as obvious, do it anyway — the obvious ones are the ones people skip and then wonder about. A single check up front replaces a lot of guessing later.

What you lose on the smaller platforms

There is no hidden trick here that the game is keeping from you. Do the cheap check before the expensive one — that ordering alone saves most of the frustration. If you are coming to this after a long break, the terminology has probably moved on.

What follows assumes you are on a current install and have not modified it. Where something depends on your platform or region, that is called out rather than glossed over. Nothing here assumes a particular playstyle beyond wanting the thing to work.

Streaming as a fallback

Where two approaches both work, the one with fewer moving parts is the one to keep. Rainbow Six Siege is not shy about hiding useful information two menus deep, so some of this is simply knowing where to look. If your result differs from what is described here, note what is different first rather than starting over.

Where people go wrong

  • Assuming a guide from an older season still describes the current version.
  • Ignoring the platform-specific note and then wondering why the steps do not line up.
  • Treating a rare edge case as the normal behaviour and planning around it.

Siege FAQ

Can I play with friends on a different platform?

Only if crossplay is enabled for that mode. Some modes in Rainbow Six Siege allow it and some deliberately do not.

Do I need any mods or third-party tools for this?

No. Everything described here works with the base game on any supported platform.

Is this still accurate after the latest Rainbow Six Siege update?

The method is; individual numbers may not be. If a value on your screen differs, trust the screen and keep the sequence.

Does my progress carry across platforms?

That is cross-progression, and it needs to be linked through the publisher account before you start playing on the second device.
