Cut Yourself Some Slack
[Submitted by: Cheat Masters ]
If you have not noticed this already, you can cut certain animations of your items and weapons short while reaping their benefits on single-player.
This is especially helpful if you're being shot up by several enemies and need the auto-injector to stay alive. For the auto-injector, once the screen tilts and you hear the re-assuring hiss, you can switch to another item or weapon.
For weapons, once the magazine total reads its maximum, you can select another weapon or item and your gun will be ready to go when you next select it. You can even start a reloading animation just before climbing a ladder and reap the benefits of the reload.

Save Your Grenades
[Submitted by: Cheat Masters ]
During the game, you will find plenty of houses that you can explore. Usually, your instincts will tell you to blow a hole in the house with a grenade. But you can save those precious grenades and use your knife to bust out the house’s door or windows. You can then jump on into the house and explore without having used any grenades!
