Some or all of the parts and/or features on this page require the Redstone Atlas Pack in-app purchase.
The retro pack is a solid rocket motor attached to any kind of capsule. It is used to deorbit a capsule. Like the Solid Rocket Boosters and the Redstone Atlas Launch Escape System, it cannot be throttled or turned off.
Trivia[]
