PSA: Portal 2 has in-game store similar to Team Fortress
Published on
Portal 2 launched today, and it includes an in-game store similar to the one found in Team Fortress 2, and it contains a "robot enrichment" feature will all sorts of goodies.
Some of these goodies include things such as new skins, hats and gestures - which will come in handy with the game's co-op feature.
A trading tab is also present in the store, but it is not active yet.
If you are not interested in the store, according to BigDownload, you can ignore it without it hurting your gameplay experience.
