| The fastest way to get the achievement is to start up good ol' stage 3 and progress through the level until the second combine mini game. As soon as you finish it, open up the start menu and quit. Each time doing this will net you around ~500 hundred kills. |

| Just kill zombies. It takes about three full playthroughs. You'll want to kill as many zombies as possible for the other Achievements, as well. Pretty simple. |
