Hello there, folks. We're going to help you get the "RED" Achievement in Lab Crisis(Windows) for picking up your first RED Key Card.
This is impossible to miss, as you need the RED Key Card to advance through Level 3(and others).
On Level 3, which looks like this:
Simply walk right and down to grab the RED Key Card
If you prefer a Video Walkthrough, watch at 3:52 to see me getting this Achievement. (The Video was created using the Xbox version, but the levels are exactly the same on Windows)
