Dead By Dawn: Bargain Hunter

Destroy the vampires on their devilish night-train before it reaches their cave! Load only the necessary bullets to kill the vampires and minimize your costs!

Use WASD to move.

Press R to open your gun's cylinder, then 1 to place in a regular bullet, 2 for a shotgun bullet, and 3 for a holy bullet. Press R to close the cylinder, then left-click to fire!  Watch out, though, because each bullet type costs an increasing amount of money.

Press P to restart, if you happen to get stuck somehow.
