Does Nuuvem use region lock?

If I buy a game in a official reseller I know the key will work worldwide. Except there is something in the destription. It would be to risky to buy a game from a shady website just to save some cents.

If a game has a BR/LatAm lock, they sell the locked version.
The rest are usually WW.

Only problem was a key that was ROW. GLOBAL has no region locks. I'll do it with an example as is easy for me to explain it. If you buy a game that has RU/CIS region lock, the ROW key will work on all the other countries outside of the RU/CIS region. If you add RU/CIS + EU + BR, it will work on the rest of the countries outside those regions.
Bought a key there, thought it was Global (was kinda new with the region lock and didn't fully understand it then), and a russian user won it, but couldn't activate it, so I couldn't deliver it. That's the only problem I had, but it was my fault.

I live in Argentina, next to Brazil. There are a few games that can only be purchased in Brazil, yet, they can be activated in other regions, such as LA Noire, Bioshock Collection. Could purchase those through a trader and activated them succesfully.

Nuuvem is not a grey site, it's just a reseller from Brazil and prices according to their economy, just as Steam Store.

I'll use Dishonored: Death of the Outsider as an example of region locks. It's price is R$70 and only sold on South America.

You need to search it on steamdb.info, go to packages

And the only region locks you'll see are from RU/CIS and China. So the key should work on the Rest Of the World.

Marking the thread to know stuff as well

if you buy from Nuuvem's brazil store, the games are typically locked to Brazil. If you buy from their worldwide store (which has higher prices) then the games are typically not region locked

Bought a GTA Collection a long time ago. Had to activate it using VPN.

On the plus side it was one of the packs which included GTA 1+2.

Just check steamdb, since as I described above, you need to check before buying, their region lock description might be just to mislead you, that's probably because of other stores pressuring them to make customers not aware they can buy cheaper without region lock from Nuuvem. Also you need some sort of South American payment and VPN system to buy there from Brazilian store, like using SA Paypal, as described in reddit if you search for it.

Bought from them multiple times and sometimes for people outside of South America and all you need to do is check on steamdb if the game you want has region restricted keys, they mark everything as Latin America only even if it doesn't apply (if it says Brazil only however it's probably true).
