I liked pretty much everything about this game and don't consider the upgrades so slack, the lack of oodles of points meant no grinding or scrooging until high levels was needed. The simple worked and was enjoyable although when only drones and heavy drones came out at higher levels the circle strafing was rendered hilarious.
b a+, but on my first run through I was gunning for a+ f-.
If you were using trial and error you're just bad at this: it's logic and zombie law, two important life skills
Old glory isn't as great as you might expect, for CTF just fully upgrade your grenade launcher quaker and buy gunners with your exess money, you can't lose if you're trying
