(Note this is for computer people, not mobile users. And also do not play this game if you do not like too much violence like burning and endless hordes.) You can change difficulty at start using up or down arrow keys, each difficulty has its unique advantage and disadvantage. When you start the game, there is walking and sprinting, press WASD to move, and hold f on WASD to sprint (sprinting is disabled on hardest difficulty obviously). Press Space to progress through different waves. Use a mouse to look and aim, but if you like to, you can press m to use arrow keys to look (left and right). Hold mouse1 to shoot/attack, but if you press m, use the up arrow key (it's weird I know :l). Finally, of course to switch weapons, you press a number on your keyboard, and press q and e on that number to go to new weapons (Note if it doesn't work you don't own it yet). And of course survive ;)
Made by OminousFord, I used different websites to download sounds, from mixkit.co and other websites I forgor. This is the "2.0" version of the original Extermination, go check it out if you want, but be warned of a VERY buggy mess. I added new weapons
