Did You Know?


The game developers were adamant about having rain during the night time New Mombassa streets segments. However, the engineers could not implement rain into the engine. It was left up to the audio department to alter the game's sound effects to provide the "feel" that it had rained earlier while you're wandering around alone as the Rookie. See more »


Regret's Assault Carrier acts different than it did in Halo 2. In Halo 2, it flies to the outer city and then jumps while in this game, it is not moving at all and then just jumps. See more »

Crazy Credits

When completing the game on any difficulty there is an epilogue after the credits. The epilogue that plays after completing the game on any difficulty besides Legendary starts off one month later with Dare and Sergent Johnson talking about the next mission. Sergent Johnson then informs the Engineer that he intends to ask it everything it knows about the Covenant and whatever it is they're looking for. If the game is completed at the Legendary difficulty level, a scene after shows the Prophet of Truth overseeing some Engineers uncovering a Forerunner artifact buried beneath the Superintendent's data core.

Halo 3 OSDT is a turning point for character lovers
17 October 2009 | by (Valhalla) – See all my reviews

You are not the Master Chief in this Game you are marines by the name of Buck, Dutch, Mickey, Romeo and Dare to save a mega city this plays like Halo it is way better than 2 and Halo Wars but on the same quality as one and 3 they are good quality game my favourite game mode is firefight (where it's multiplayer and you shoot regenerating brutes only after death) my favorite handgun is that brute one where it fires like a machine gun but has some knives on the bottom that's the gun I like. my favorite turret is the missile pod with heat-seekers. my favorite 2 hand gun is either the sniper or the rocket launcher. "I like this gun" - Men in Black (1998). Plot: you are clearing a mega-city for Aliens with your OSDT squad and not letting any of them get out to destroy Earth.
