The R&D Lab is an area in the technology park (the fourth and last office of the game) accessible after certain requirements are completed. R&D Lab grants access to the new area, new game development options, new engines, and new income opportunities. Depending on the budget you allow it, the R&D Lab produces a certain number of R&D points that go towards the active project. If you do not have an active project, it will produce generic research points.
For the exact requirements for each of these, look at the Research Unlocks page.
