@blueburp17 Fuel is already easy to come by in this game. Putting in a gas station would ruin the game through everyone buying keys in the shop/refining weapons/ etc. Besides, the devs are kind enough to allow a premium currency in the game to be obtained for free, so I don't think any of us are in a position to complain.
Found a glitch in the last level on the hardest difficulty. When you hit 'Q' to switch to your secondary, your guy uses the pills instead. And if you hit the button for pills anytime after this, you lose your guns and can't shoot.
