If you're not among those who received a Rising Storm 2: Vietnam key for the final beta by signing up on the official website, we have good news under the guise of 550 codes that will grant you immediate access. The test is already live and will go on until Monday 15th.
Do note that you won't need to grab another code in case you were among the winners of our previous smaller giveaway. Furthermore, if you have already purchased the game through pre-order or buy the game while this beta is active you will receive a warning message in the Steam store about already owning a duplicate product. You can safely ignore this warning, and go ahead and install the beta - the beta will be removed at the end of closed beta testing and the full game will be unaffected. Once the full game releases it will download into their library with the “Thanks For Testing” DLC. Again, this should only affect people who have pre-ordered the full game already and are trying to install the beta or try to purchase the game after having redeemed a closed beta key.
In case you're not familiar with Rising Storm 2: Vietnam, you may read our PAX East 2017 interview with Tripwire as well as a general overview of the game below.
