STFC Commanders level 20 and higher can construct the War Room once they have completed the Show Us You Mettle mission.
Scopely recently released a major update for Star Trek Fleet Command (STFC), and it introduced numerous new features that you can enjoy.
The update revealed that players can now construct the War Room, which will help you obtain significant rewards for yourself and for your Alliance.
You need to partake in player-versus-player battles to earn points in the War Room. Since the War Room’s release, several Commanders have wondered how to construct the new building.

Unfortunately, only players level 20 and higher will be able to construct the War Room, but you also have to complete the “Show Us You Mettle” mission to unlock the building.
When you have completed the quest, you can construct the War Room to earn rewards. Commanders must annihilate enemy ships and steal resources to earn points for the War Room.
You can earn additional points for performing these actions within Territory systems or during the Infinite Incursions activity.
Once you and your Alliance have accumulated enough points, you will receive a variety of rewards.
That being said, it is believed that you do not have to be part of an Alliance to earn the rewards, but it will take you longer to complete every milestone as a solo player.
On the official STFC Discord server, Moderator, Zabatiz, mentioned that the War Room was specifically designed as an Alliance activity and therefore, it will not score any points if you are not in an Alliance.
If you are not in an Alliance, we recommend that you check whether you earn any points for defeating other players.
If you do not earn points, you may have to join an Alliance to get the War Room’s rewards.
Rewards
If you reach specific milestones in the War Room, you and your Alliance will receive an abundance of rewards. Players will earn basic resources, materials, ship parts, emblems of honor and Seals of Ko’tal.
This new Seal unlocks the exclusive Tactical Warmonger Research Node. Furthermore, you will benefit from numerous buffs; and War Room Shield Health is increased from 20% to 3200%.
The War Room officer stats are increased from 10% to 2250%, while the War Room Isolytic damage is increased from 0.50% to 50%.
Upgrading the War Room
Similar to other buildings in STFC, you can upgrade the War Room to maximize the rewards that you earn. The rewards from the War Room significantly increase with its level at specific tiers.
This means that for every 5 levels that you upgrade your War Room, you will receive more rewards.
Keep in mind, however, that upgrading any building in STFC requires numerous resources and materials.
How to join an Alliance
Several Commanders believe that STFC players cannot construct the War Room if they are not part of an Alliance.
To join an Alliance, you have to select the Alliance icon, which is in the bottom left corner of your game screen.
You can then scroll through a list of Alliances ranked by their power and other statistics. You simply have to select an Alliance and request to join.
If your request is approved, you will receive a notification and then you will be able to enjoy the War Room.
