32. Killzone 3 (2011)
Final Level: "Fleet Battle"
Why It Sucked: We get that the Helghast are the bad guys, but genocide is pretty much never cool. And then to strongly imply that the target of said accidental genocide-the dude they were actually trying to kill-escapes? Double not cool.
How We Would End It: If Stahl is going to escape put in more about that so we'll anticipate a Killzone 4.
