AM2: The Final Guide.
Going for gold

Week #4

Week 4 Day 4
Today we are only cumulating more R&D dollars.
Sold should be at least 470M of R&D dollars.

If you are already at 500M start to CBIB research (YMMV)
If you are at 480M but below 500M, start (finally) the Cargo Research (20M, 4h).
This will save you a bit of time later.
