Halo 2
Halo 2 is one of the best first-person shooters of all time, but sadly still has one of the worst video game endings in recent memory. After battling your way not only through The Flood and The Brutes, you are met with a fairly entertaining boss fight against the chieftain Tartarus. Then it decides to not tie up any loose ends, leaves Cortana with The Flood, teases a more interesting story and has Master Chief end it with the phrase “Finishing this fight”.
Essentially this makes the entire story of this video game feel less like a stand-alone tale, but a prologue to the next game. Just because this is the second game in the series doesn’t give it an excuse to basically ignore all of the storylines that it has conjured. Halo 2’s ending is nothing more than a big advertisement and set up for the finale, lacking in any sense of drama or flair that the franchise is known for.
