I myself am experiencing the following bugs:
In the shop, I cannot select the weapons I want to use in endless mode. When I try to go to that screen, it simply pops up an alert saying that Dr. Bastard will select my weapons for challenges but I can select my weapons for Endless. I already know that, now how do I select said weapons? Lol
As Dark said, there is a bug with diamonds. I also cannot change the cards in endless mode.
I do wish the music wasn't quite as loud as it is sometimes, as it makes things hard to hear. Endless mode can be pretty chalenging at the beginning because you're not introduced to most of the higher level zombies that tend to show up. Collecting coins can be a dragging process, at least for me... I'm getting better though. I can't wait until I get really good. Challenge mode isn't too easy either... but I do like it. I really hope they release more challenges soon! But I'd rather the bugs be fixed first. It's not unplayable for me, but bordering on frustrating.

WARNING! THIS POST MAY CONTAIN SPOILERS! I DOUBT IT THOUGH!

Hi all. So I'm suffering a bug was wondering if anyone else is, too. In the zombie horde level in the city crossroads arena, I kill all the zombies, but then theres no buzzer. I just stand there and nothing happens. I can shoot, I can turn around, I can switch and reload weapons, I can swing my melee, but nope. nothing. And in endless. Sometimes, the game will just freeze. There'll be a zombie within my melee range, for example, then it just disappears, as with all the zombies, and I can do nothing. when I turn voice over back on, I'm not in the pause menu, the game is just frozen.

I found another bug. I was able to buy the sonic cannon but for free. Oh I'm not a cheater, so when the next update comes out I'm going to totally redownload the game so I don't keep it for free, but I found it pretty damn awesome.

@Grryf, with the screen locking, go into settings/general/autolock and turn your autolock off. I've had to do this for quite a few games including Ticonblu. Generally anything that has sound and might involve me not touching the screen for a while or reading with vo.

I agree about the game, though the bugs with death have been a pest. With respect to Ios versions I was just wondering if perhaps some of the more serious bugs people reported that I hadn't experienced myself like the whisper freeze in endless mode came from Ios 8, though possibly not. I do know the game has problems displaying on Ipad and can't even be bought past the initial "which control method would you like" screen, which is a shame. Hopefully we'll see some major fixes soon.

@Dan, missing content? I know one of the arenas has a "coming soon" note, but I didn't notice a lot else missing, unless you count collecting the diamonds in endless mode. Then again I didn't have chance to try the game again yesterday, so it's possible I missed some stuff in the armery.

Looking at the game and the way it is designed, I do wonder if more challenges, weapons etc might be added in the future. I'd be happy to pay for extra content like that with an in app purchice, though I am glad the in game coins and diamonds are only possible to earn by playing sinse it would take the fun and reward out of multiple goes at the game if you could simply buy all the upgrades with real money, as unlike with most games that have an in game currency earning extra coins (and hopefully soon diamonds), is rather fun!

well I personally believe that more than one arena is missing, for there needs to be at least another to introduce other zombie types, and the full crowd one on top of that.
I am perfectly fine paying for add-ons for this to support the dev, but with the state this is in, I just feel that the game has been rushed and therefore appears like a beta to me.  That's not to say I don't find it incredibly enjoyable though.
Anyone got tips for the riot zombie? that bugger gets me every time as I can't yet figure out when he lets the shield down.

Hi,
I'm wondering how many more arenas are in the works, after all I think it'll have to eventually build to some sort of conclusion.
The stufff they could do though, wow, let's just say I hope they do the crows arena because that is going to be awesome.

I just clicked into it in the shop and it said buy for 0 coins.

Hi all. So, I was playing challenge mode and I got to Zombie horde. The problem that I am seeing with this challenge is that, when I beet the level, everything is silent, the buzzer doesn't go off, and I can't really go onto the next challenge. I have tried restarting my phone and the app several times but no luck on getting any farther. Has anyone experienced this and a work around for right now till they get this bugs fixed? I'm using an I-phone 6, 64 gig

By the way, I don't know if anyone has discovered this yet or not, but the maya ruin challenge is already very much available in deed. Maybe it's a bug, me being able to access it even when I'm stuck on zombie horde in the city crossroads, but it's certainly there in any case. In fact, there's another zombie horde level in maya ruin, so I now have two zombie hordes in different places that I'm stuck on and haven't beaten yet. :-D

Whether this is a bug and it should only become available to play after the entirety of the city crossroads has been beaten first or not, it certainly shouldn't be saying coming soon. :-)
Just to let everyone know.

I agree, though, that if there are no challenges with the actual crowd in the arena yet, and they are not going to be added as opposed to the original plan and advertising, it would be extremely disappointing.

actually you can change your loadout. to bring up the button to go to the armory, in the tarot card screen, double tap where it shows your coin amount. if you go to where it says something about doctor bastard, then go back one, you'll find it. hope this helps.

at dark, yes, I am aware of that, what I meant was sometimes the armory doesn't show up sometimes.
