Technology
In general Aliens technology is TL9, and is reasonably hard science.
A few exceptions have been made (FTL travel/radio, artificial gravity)
but in general if unsure whether to include super-science,
then leave it out. A few other technologies
(mostly biotech) are little used because of public opposition.
- Power plant technologies are TL9, with fusion used for almost every
large ship or colony. However power cells for personal devices don't exist,
and advanced batteries have to be used instead.
- FTL technology is closer to TL10. Warp drive is available at ten times
normal cost, with speeds of up to several hundred cee. Slow FTL radio is
available, with limitations on range and high energy costs. FTL sensors
and weapons are not available.
- Gravitic technologies are in their infancy in the Aliens universe.
Artificial gravity is available for ships, but contra-grav, grav-weapons,
and other grav technologies are not.
- Computers come in two distinct types. Everyday computers are simple
TL9 devices. However TL10 bio-computers are also available at fifty times
normal price, and these are common in humanoid androids. The limiters that
prevent computers becoming sentient do not exist for either type, so
large computers must be watched carefully.
- As a result of not having power cells, slugthrowers remain the
primary infantry and small vehicle weapons. All TL9 weapon types are
available, however caseless rounds using advanced ammunition types
(HEAT, APS, APEX, etc.) are the most common sidearms.
- Medical technology is at overall TL9. Hypersleep capsules are available
to safely put a person in suspended animation for hundreds of years, and
Autodocs replace doctors on most small ships. Braintaping is available,
but high costs and ethical considerations limit its use.
Similarly the sciences of genetic-engineering and cloning are both at
TL9, but are not applied because of international law.
- Nanotechnology is in limited use (largely in high-tech construction,
medicine, and terraforming) but general purpose nanites don't yet exist.
- Terraforming is a highly developed technology, equivalent to TL11.
Usually atmosphere processors are used in conjunction with bio-engineered
algea or specialised nanites.
