Please read everything here \/ At the start, even though it looks like the green flag is on, it may not work. So please double click the green flag. Please DO NOT switch on Turbo Mode as the zombies will run super fast, while the bullets are restricted by wait blocks. Up arrow to angle upwards, down arrow to angle downwards, or use on-screen arrow keys. X to cancel all angle adjustments. On screen arrows cant make you go forwards or backwards. left and right arrow keys to go in either direction. W A S D follow and have the same purpose as the arrow keys. On screen buttons are for gun purchases. Use the 'shop' button to access the shop. First gun costs nothing, second costs $100, third $300; fourth $900 and the last one,which is very overpowered, costs $10,000 and leaves bullets in a minefield-like position, Making every zombie that walks over it die. My highscore for auto direct (because I set it at the start of the game) is My game screen is particularly small, if you have noticed, compared to @simu2008's one. Unless you want to be adventurous, please: 1. upgrade auto-direct twice, not once, and if you accidentally did it only once, you can press the switch to turn it off. 2. Only purchase auto-direct if you have gun responsiveness upgraded to its maximum.
Thanks to @simu2008 for idea of Zombie shootout by showing it to me on his Scratch Desktop (I suggested updating sprite position instead of detecting mouse position as he said detecting using clones was lnot working. There are other things I edited which I feel makes it incompatible with Scratch Desktop.
