The “Chain of Command” achievement in Left 4 Dead 2 is actually rather easy to get, provided you can get your hands on a chainsaw. To gain the “Chain of Command” achievement, you’ll need to kill 100 common infected zombies with the chainsaw – which is actually a lot easier than it sounds. You can either play through the game normally, using the chainsaw when you have the opportunity, or you can use this simple trick to quickly rack up your 100 chainsaw kills:
Get yourself some bile bombs – the more, the better. Pipe bombs will also work, but are more risky. Find an area with a lot of zombies in it, and throw your bile or pipe bomls for each bile or pipe bomb, so the more of these you have, the faster you’ll gain the “Chain of Command” achievement.
