Hey, thanks for playing once again!
Apologies for the info text being hard to read, had a few other people say the same. I kind of tried to keep the weapon descriptions compact, but I clearly went too far with the size of the text. Will make it much larger and readable in the next build for sure.
Things got really insane during your playthrough as you were setting off multiple reinforcement calls at once, and you handled it really well! Loved seeing you manage to dodge the fire from the gunships and take out incoming transports each time.
Did you try holding down the rockets when firing them, or did they always only fire once if you clicked and held down? The main difference between the rockets and missiles is that you're supposed to be able to rapid fire them more as a crowd control weapon at the cost of not being able to lock onto things, so spamming them at the command center would've probably worked. I'm just wondering if something went wrong and they weren't responding to you holding down right mouse button. It is possible to kill the command centers before they call for reinforcements, but you need to focus your fire pretty hard on them -- best bet is not to use missiles or grenades and just your primary weapon. (Although the incendiary grenade isn't too bad if you use a few at once)
The boost/overdrive you can actually hold past the line on the bar. It's just once it passes and you release shift, you have to wait until it recharges forward from the line to boost again. No damage penalty or anything.
Also this new mission kicked my own ass pretty hard so no worries about the repeated D ranks, haha. You can actually take one or two hits and still get an S rank, but you'd have to do the mission under 2-3 minutes so it gives you a time bonus. You can take as long as 5 minutes on a mission and still get S if you take zero hits, but any longer and it'll start to detract from your score. Maybe this system is a bit brutal, but the ranks don't matter too much in the grand scheme of things I think...
