Hey all, it has come to my attention via the mechlab video and a few others from comments, that the mechlab should have color coding to help visualize the various weapon systems. I figured this should be an official suggestion, so reposted here.
Good point, MW4 had this and it made it easier to sort through the weapon types. But if you notice weapons appear and disappear depending on the weapon type the section of the mech takes (3:44-4:05 in the video). This may make organization easier than in previous games.
