When a cooperative member initiates a research project, other cooperative members can temporarily assist with the project to reduce the development time. Each member can only assist in each development once.
Assisting another player is completely free. Assisting members grants you daily 5 activity points. If you've joined a new cooperative within the same day, you must wait until the next day to earn points.
The duration of a research project with assistance from 49 members decreases by %33. For instance, a 100 minute research project, if assisted by 49 members, will decrease to 67 minutes.
