Repair Platforms are structures available to all three factions. The TEC and Vasari factions require only one military lab to research this structure, while Advent requires two. The Vasari version is referred to as the Regeneration Bay. The repair platform does exactly what it claims to do, and very effectively repairs nearby units. Its repair speed is so fast that it's actually very useful even in combat situations. Many players swear by repair platforms and use them as their primary defensive structure. It's not uncommon to see this as the first research a player makes at the start of the game.
