5. Halo 3: ODST
Originally conceived as a relatively small project, planned to be released as downloadable content for 2007s Halo 3, ODST eventually transformed into a standalone title, and was released at full retail price. Once people stopped complaining about having to pay full price for what was basically extended DLC, they found there was actually a lot to like about Halo 3: ODST. The games night sections were both atmospheric and visually appealing, whilst the narrative delivery provided interesting snapshots of the battle for Earth. ODST also brought Halo fans the multiplayer mode Firefight, which offered some nice variety to online play. However, there were still problems with ODST. For starters, playing as Rookie, a marine, was nowhere near as epic as stepping into the shoes of Master Chief or other Spartans. With the absence of the Flood and Forerunners, combat became increasingly repetitive as the game progressed, with the Brutes just not managing to fill the void left by the Elites. Throw in the fact that, by its very nature, ODST just could not hope to be as epic as any of the main entries into the series, and it is easy to understand why it is placed 5th.
