So, I think this should be an impossible badge. Most impossible badges are for endurance/persistence. This is much longer than most hard badges. (And like the other people have set, the gear rewards are dumb. You have to beat a level 20+ level to get a level 4 piece of gear, really?)
Not sure I'm digging the new method of fighting. It makes fights take a long time, 24 adventures would be painfully long. The debt thing makes almost all your winnings at the beginning just go to interest and the shop is a little lame at the beginning too. It generally costs more to pay interest on the shop than you expect to make.
Alien campaign, the bots are dumb. The enemies have way too much health. It was a cool game until I started having to repeat missions 10+ times to complete them.
Game is somewhat random. Your men don't block for you. Sometimes they don't even run toward the ball. If you swap to a man close to the ball, sometimes it takes half a second to register and he runs away from the ball during that time.
It bugged on me and made me play division 2 twice. In the end, I just wanted it over.
This game is way too hard. The big zombies hurt you way too much. Getting past the first couple of levels takes a little too much patience to be fun. I can't imagine what the harder difficulties are like.
