Ugh, now you've got me started on my Gun Bros. rant.
I like the game. It's cool and has nice controls. However, it is the most bug-filled mess I've ever played. Just to do a quick rundown:
--On startup, it doesn't always register the login properly, meaning it doesn't credit you for the daily sign-in. That means I have to start the game AT LEAST twice 95% of the time I want to play.
--The left thumbstick will just fail at random. I'll just be moving around, doing things without issue, then my character can't move. I have to tap and drag the thumbstick 2 or 3 times to get it to respond again, and it's stupid.
--The Refineries will occasionally break. This kind of coincides with the login problem. You'll finish a game, go to use one of the big-money Refineries, only to have them all locked. It's happened to me on SEVERAL occasions.
--You'll lose your purchases at random. I had gotten all of the purchase Achievements on the game at this time. I then wanted to try out a new gun, so I bought it. Next time I came in, I had lost ALL of my unequipped purchases, meaning several guns, dozens of armor pieces, and 50 health packs. It also meant I had to rebuy the Coronal Ejector, which took a bit of farming to get the 81,000 coins necessary to repurchase it.
Again, I like the game itself. There are just too many crippling bugs. I'm almost through Revolution 6 (didn't get to play much yesterday...), but I'm trying to power through to get the last 2 Achievements, at which time I can delete this broken mess from my phone.
