Wow, a new update right when I installed the 5th version, yay! It apparently has lots of good stuff, such as finally including the type of agent next to their names in the soldier list, freaking finally. That was a life saver. Also, AI Units are also very rare to acquire, which means I have a surplus of them due using a save before the update.
Just to know: Why make AI Units so hard to acquire, when initially they're not that good with the scout drone chassis (and the medical one as well)? Until you unlock HWP tech, they're not that good compared to any regular agent, and unless you luck out and unlock the rocket launcher scout chassis early, they won't be able to contribute much to fights.
