Which digital format of Portal 2 should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

If I buy the account format of Portal 2 , will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Why is the Steam Key of Portal 2 safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Portal 2 to your game library. The account format requires more complicated steps and is more prone to errors during activation.

What issues can arise when activating a Steam Key of Portal 2 ?

The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Portal 2 , and they will provide a new key. You can also contact us, and we’ll help you out.

These stores rarely delay game deliveries.Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.

Portal 2 is a 2011 first-person puzzle-platform video game developed and published by Valve Corporation. Like its predecessor, Portal 2 primarily comprises a series of puzzles that must be solved by teleporting the player's character and simple objects using the "portal gun", a device that can create inter-spatial portals between two flat planes. The game's physics allow momentum to be retained through these portals, which must be used creatively to maneuver through the game's challenges. Most gameplay elements of the original Portal were retained in the sequel, and more were added to Portal 2, including tractor beams, laser redirection, bridges made of light, and paint-like gels that impart special properties to objects they cover. These gels were created by the team from the Independent Games Festival-winning DigiPen student project Tag: The Power of Paint.

This game keeps everything the prequel had, but adds more story progression, but to me it's always welcome. The game still requires a lot of brainpower

Very long story mode took me around 18 hours to complete the game but its not only story mode you can try speedrunning some stages in the game you can also get workshop maps or make your own workshop maps and its an overall fun game to play especially the coop mode with a friend.

This was a rather amusing game, and I cannot emphasis just how good it is. Compared to Half-life 1 & 2, this game is full of wit and comedy as well as amazing game mechanics.

This game is amazing. A real brain teaser at many times! It introduced a clever way to solve puzzles. The game had hilarious moments that I think made many laugh around the world.
