Since I Haven't Downloaded Warframe Through Steam, Is There A Way For Me To Open The Steam Tab?

[Goosmo]

I really don't wan't to redownload the game through steam.

[Corpsman]

Start the Steam launcher

Go to the games meu at the top.

Select: Add a Non-Steam Game to My Librabry.

Select Warframe from the list.

 

Once done exit (not just close but exit) the Steam launcher.

At this point Warframe is added to your Steam library and you can use the store to buy one of the packs.

 

[edit]

Might want to delay buying anything this way. Just tried it myself and it did allow a buy due to the launcher detecting that Warframe was in the library but it created a duplicate entry for Warframe requiring me to download the game again to actually activate the pack.

Waiting for a response by Valve on how to solve this

Apologies for not replying for so long.

Anyhow you need the steam version of Warframe to be able to apply items bought through steam. This due to it containing some extra code tying it into the steam network.
