This game has a few bugs.
Sometimes, the shop is completely blocked, making it impossible to continue.
And the laser also completely kills the cannons.
This is weird. I play normally and my guys turn into green zombies. I make them rest but their condition gets poorer and poorer. How do you prevent the zombie condition?
I'm on the train part of near the beginning. I got the first two codes after Gastave found the thing that hopped away, but I can't get the third code. Is there some hint or somewhere?
