Retro Rockets v1.00 ReadMe & License.txt

Retro Rockets OXP by Thargoid.

The Ships Systems Department of the Aquarian Shipbuilding Corporation would like to present to you their latest products, retro rockets. These are a redirection of the ships jets to provide reverse thrust when triggered (with the "n" key, after selection with shift-n). The rockets requre 1ly of witchspace fuel per use, and must be allowed to cool down for at least 30s between uses. Automatic system interlocks are include to ensure this.

Galcop have also stipulated that retro rockets are not usable within the aegis of any of their stations, so an interlock will trigger if such an attempt is made. The interlocks will also trigger if the ship is under either fuel injection or the torus drive, as the use of retro rockets under such conditions could cause serious hull damage.

The system can be purchased and fitted at any good tech level 9 or higher station, for a cost of 500 credits.
