Use Your Chainsaw Tactically
Your chainsaw is another pretty handy item, but you need to use it sparingly. While it’s certainly fun to use it on every demon you see from the moment you get it, you’ll soon find yourself regretting your decisions because of its fuel limitation. The chainsaw can only be used as long as you have fuel. The fuel gauge is displayed in the bottom right corner of the screen and is made up of three sections. Using the chainsaw on a small enemy in Doom will use up one section. The larger the enemy, the more sections of your fuel gauge the chainsaw will eat up. Therefore, you need to use it only when you really need to get rid of an enemy that’s all up in your face.
The chainsaw, like Glory Kills, also gives you a little bonus for using it. Once you’ve dismembered whatever enemy lay in your path, yellow blobs of ammo will spill out all over the floor. Pick ’em up and your ammo levels will be resupplied. Therefore, the best time to use your chainsaw is when you’re running out of ammo and still have enemies heading straight for you. Always keep one section of your fuel gauge spare for these kinds of emergency situations.
