The Medium Weapons Platform (MWP) is a 3x2 room unlocked at level eight. When built, the MWP unlocks the Laser Blaster, Railgun, and Photon Disruptor. The player can then select one of the three weapons to be equipped on the MWP. The weapon chosen will then replace the MWP. In addition, any upgrade done on one weapon will also bring the other two weapons up in level.
Switching the weapon mounted on the Medium Weapons Platform costs Minerals and requires build time that differs by weapon level, as shown in the table below. These costs are incurred each time the weapon on the MWP is changed.
