The following is a list of mentioned technologies in the Alien Swarm universe which miss too much information to justify their own articles.
Hypersleep is one of the core technologies that makes interstellar travel possible. During travel colonists are suspended in cryo tubes, in which they may sleep for many years until arriving at their destination. While in suspended animation colonists do not age but are vulnerable to swarm infestation. This technology is used by Spacefarer Inc.
A Starport is an extraplanetary, orbital space station used for the refueling and maintenance of starships, or for the short term storage of perishable cargo, precious mineral, and rare gasses. Starports are much smaller than Space Stations and use a rotating staff compliment, not designed for long term habitation. Also known as a Starbase.
