That game was an impulse purchase for me. Because I like zombies and despite the simplistic graphical design, it seems clear to me, that the game oozes atmosphere...

I played for 4 hours and until now, I really enjoyed it, made good progress etc. But now I am stuck in Level 5, or...?! I made it to the metro central station and have to find the museum now. I think, I only died 3 or 4 times max to finish the previous levels and usually found at the least the level objective key card on first try... but this level now... I tried it certainly already 10 or 15 times and not even a key card found... this is the first level, where it feels like I'm stuck in dead ends all the time... I am not frustrated, yet... but I am losing interest xD ...

Hmmm, I am yet to get stuck...

I'm an explorer at heart, though, so I go through all the map before even trying the very last bit (around the exit icon).

If you do that as well, then maybe you have the same problem I had at some point: I didn't use the torch unless it was really necessary, as I wanted to be as stealthy as possible.
But at some point I actually read the description of the torch, and it says it reveals loot.
And lo and behold, I do find much more loot now that I'm regularly using the torch (carefully, though)...

If you've done all that, you can always try to restart the level completely, or even redo the previous one (though they are randomized anyway).
You can even start with a new character.

But if that still fails, you gotta take it to PuppyGames (if they ever come here).

Thanks for your comment, I will have a look into it, give it another hour and see, if I can make it. I use the torch all the time and always find lots of loot... only this time in that particular level, no loot worse mentioning besides some chang in wallets...

I avoid all things zombie, but made an exception for this game. I really like it.
I don't get stuck in that sense, I just keep dying all the time. But the atmosphere is so great, that I just keep trying again and again. I love the stealth part. I'm not a fighter - at least not when zombies are involved. Me too (exploring, stealth and the torch desciption).
I restarted after I realised, I missed most loot, because I didn't use the torch.

I unlocked the police officer, but still play with the secretary (?), the starting unlocked character. I love, that you discover recipes as you play, but I wished there was some hint as how to unlock the other characters.
