The third act.

I cant even count how insanely unforgettable the third act in Halo: Reach´s outstanding campaign was. Hearing Captain Keyes´s voice for the first time in over 9 FRIGGING years and how the game brilliantly lingered towards the storyline in the first Halo game, all of it was fabulous. The ending however, took the cake, after being left behind, you, Noble 6, fought until your last dying breath and that moment was so captivating and memorable that it makes me ecstatic just writing about it. Bungie went all out with Halo: Reach, and boy did they suceed.

Would you kindly?

BioShock was a twisting and dark game in every concievable way, and the story was the best thing about it. After you are set lose within the cryptic corridors of Rapture, you are assisted by a man known as Atlas who ask´s for your help to save his family and kill Andrew Ryan, Rapture´s founder and mastermind. How Ryan and Rapture fell from grace is an entising mystery that stalks you all the way through to the shocking reveal. Because it seems like Atlas is VERY thorough when he asks you to do something with the prashe, ´Would you kindly?´. And when you approach Andrew Ryan´s office, ready to put him down, he asks if the aforementioned line rings any bells. It then turns out that Atlas is infact Frank Fontaine, Ryans most daring competetor and that he had brainwashed you with the line, ´Would you kindly?´so every action in the game had been against your own will and he had just use the death of "his family" as a scapegoat to question Ryan´s morale, who also turns out to be your illegitimate father. Oh by the way, that plane crash in the beginning of the game, that was all you.

The endgame.

Mass Effect 2´s endgame was so excting that i nearly passed out. After all the time you had spent recruiting and gaining the loyality of your shipmates, seeing them dropping like flies (which happened during my first playthrough) was almost heartbreaking. Despite the boss being quite easy (albeit larger than life) that final run towards the Normandy and every other event that transpired during the endgame had me mesmerised, and i loved every moment of it and when i finally leaped onboard the Normandy and saw the achievement pop up "Against all odds" (survive the suicide mission) i yelled in joy and excitment, even though it was just me, Miranda and Jacob that survived with everyone else being completetly killed off. Its stunning.

The nuke.

Sure enough, the main protagonists never talk in Call of Duty (With Black ops being a major exception) but the first Modern Warfare did a great job of attaching you to the brave soliders you were playing which made it all the more shocking when the nuke at the end of one the levels as the Marine killed everyone, even more, we had to experience the last moments of his life as you crawled out of the chopper wreck and saw buildings crumbling and playgrounds on fire in an awesome kin to the opening to Terminator 2: Judgement Day. It was dramatic and memorable.

Nicole is dead.

Isaac didnt exactly have the time of his life onboard the derelict, horror infested ship USG-Ishimura. Necromorphs are after him and he is destined to be reunited with his girlfriend whom he actually comes in contact with when he prepares to extract the artifact known as the marker. However, he is then struck with a horrifying truth, that his girlfriend committed suicide by injecting poison in her veins in order to avoid the necromorphs and presented a tearful goodbye through a video message, and the marker had caused Isaac´s visions of her, causing him to suffer from a severe case of Dementia.

It was all a simulation!

The Assassin's Creed series is very well known for having multiple, complex storylines that interfere with one another and was it was quite a shock when all of this was revealed in front of you. Because the clever thing was that none of the trailers revealed the second storyline that involved Desmond Miles the bartender and most critics did not give it away, so it was quite was a shocker that just minutes after you booted the game up, you were thrown out of the game and learned that the world of Assassin's Creed took place within an Animus, a device that can read your DNA and let you stimulate the experiences of your anchestors. It was clever and unique at the time, though it would have been even more shocking if they had saved it all for a massive twist ending.

The ending.

Limbo is one of those rare cases where an ending that is left to interpretation works really well. Limbo has no storyline, you wake up on your back in the middle of a creepy, dim lit forest and the vague backstory has you searching for your sister. As you start to navigate the treacherous path, you encounter things that would like nothing more than to outright kill you. However, after solving the last puzzle, you are sent through a sheet of glass and then wake up where you started the game and you then encounter a young girl, presumably your sister, making a makeshift grave and then stands up, horrified at your presence. This is where the game ends abruptly. Many believe that the boy died in a car crash (hence the travel through a glass sheet)and that the boy encounters his biggest fears such as spiders, water and other creatures and his journey to heaven is to be reunited with his sister. Interestingly enough, when you return back to the main menu after the credits, you see a broken ladder and below two graves with flies soaring above them, assuming that the boy and his sister was playing before the boy fell down and died..Perhaps. Regardless, the way Limbo reinforces you to let go is absolutetly spell binding and the ending is a lot better for it.

You are the bad guy!

Star Wars: Knights of the Old Republic was awesome because it was truly the first RPG to cross into the Star Wars realm and provided the same, excellent and tactical combat system from Bioware´s previous games such as Baldurs Gate and so on. The game also oozed Star wars everywhere, from the combat, to the character interactions and the exploration. Even more so, near the end it was revaled that before you lost your memory and woke up on an Alliance ship, you were Darth Reevan, the apprentice of the main villan in the game. R U shitting me?

Reznov is not real.

What made Black ops triumphant from other Call of Duty games was its story. Hellbent on cold war conspiracies and other mindbending plot points, Alex Mason´s globethrotting adventure was in the shadow of a dark truth the entire time. You were brainwashed back at the labor camp of Vorkuta and was turned into a sleeper agent that was programmed to assassinate John F. Kennedy and after Reznov´s demise after the Vorkuta escape, he was stuck in Mason´s head and eventually became a dominant personality that almost devoured Mason, oh and your interrogators turned out be Jason Hudson and Weaver, your CIA handler and russian colleague respectively, oops.

Dr. Janice Politos true identity.

We all knew Shodan, the main antagonist from the first System Shock was gonna be in the second, right? She was after all on the front cover of System Shock 2 so she had to be there. But that is something that eventually slips past you when you wake up on the overrun ship Von Braun and are contacted by a scientist named Janice Polito who guides you throughout the game and helps you overcome he many enemies and obstacles that stands in your way. However after many hours you are ordered to meet her in her office, only to then be greeted by a dead corpse and a very unsettling voice. "The polito form is dead, insect" and so it hits you, like a truck driving right into a concrete wall. Janice Polito was dead, and Shodan used her as a puppet to gain your trust, it makes you slap yourself in the forehead and go "how did i not see that coming?", its an awesome twist alright but no where near as good as Bioshock´s shocking revelation.
