When you need to run a long way and have some objects with you (for example, a
non-explosive barrel), if you have the Gravity Gun, use it as cover, and run (while
facing the enemy) to the other side. Then if possible, shoot the barrel at the enemy.
Note: Make sure there is only one enemy when doing this. Also, make sure the
object is indestructible, and most importantly, look at the enemy and see if you can kill
it with one shot.
