# 17.2 ## 64 Research System
- Added a research system to the game. You can access the research screen from the main menu. Researching a module has two effects. 1) The researched module type becomes available in the sandbox mode. 2) You can loot high quality modules of this type in the exploration mode.

- You can now assign two keys to the revolute joint.
- Added a voice message when a sector contains a boss enemy.
