About This Game

Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original Portal over 70 industry accolades and created a cult following.

The single-player portion of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers. Players will explore never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game.

The game’s two-player cooperative mode features its own entirely separate campaign with a unique story, test chambers, and two new player characters. This new mode forces players to reconsider everything they thought they knew about portals. Success will require them to not just act cooperatively, but to think cooperatively.

>Much better graphics than Portal 1, adding some green colour in these dully science laboratories

This is a fantastic game! Yes, get it. If by some chance you are actually reading this review it is because you are unsure. Don't be. Just buy the game. That is unless you do not like thinking and puzzle solving....if that is the case... Doom!

Oh thats not enough?

I love this game, so much. The backstory and hidden secrets capture my attention. YES YOU SHOULD BUY IT! The puzzles arent that hard, well some might be, but when you figure them out you feel complete... But! YES BUY IT! This game is amazing, really, i dont want to give much away in the game its self. You gotta lose yourself in it and look for hidden clues, hints, then when yout hink you found one, look it up and find a whole huge backstory on it. It's amazing to go through it and figure out all the secrets.

Co Ops nice too.. trolling your buddy is fun. "Oh you want me to stand here and give you a bridge?.. okay! -moves when friend is on it, friend falls to death- HAHHH!" <-- the life of Co OP, ruing friendships but its worth the laugh.

Portal 2 is a first-person puzzle game developed and published by Valve and released in April 2011. Portal 2 incorporates a campaign that allows you to solve challenging puzzles while treating you to a strong and simple storyline. This review will discuss the campaign, the voice acting, dialogue, and the co-op feature.

Portal 2 features a quality campaign that emphasises creativity through overcoming puzzles and excels in superb voice acting that includes funny humour. You begin the campaign as Chell, a female character holding a portal gun. Chell completes tests using her portal gun while being monitored by AI computer system Glados, voiced by Ellen McLain. Chell completes these tests while listening to Wheatley, a programming core that is voiced by Stephen Merchant, in which he wants to escape the facility. The puzzles are diverse and I do not grasp the notion they are repetitive. They do in fact become more difficult as the game progresses which is due to new things being added to each level that add a new layer of complexity. For instance, some levels feature turrets that can spray bullets at you, which you must destroy before advancing. Portal 2 has a really good ending that ends the story with an amazing final mission that mixes both emotion and intensity. Furthermore, the ending smoothly transitions into the credits that completely alter the atmosphere into a beautiful light hearted finale, complete with a song sung by Glados. Briefly, the single player experience does have some annoying glitches with freezing when pressing R for the feedback prompt and frequent crashing via alt tabbing. These two issues had minimal impact on my experience of the game.

The dialogue enhances the single player component by incorporating witty humour with dialogue that provides excellent characterisation to the characters. For instance, events showcase characters change of heart and provide some emotion to their robot personalities. This creates a juxtaposition of humans and robots because the game reveals human traits of emotion, self-interest for personal gain, and relationships with other individuals within Glados and Wheatley, both whom are robots. The voice acting in Portal 2 complement the strong dialogue because individually, Stephen Merchant delivers a memorable and excellent performance for Wheatley by striking different voice tones that match different situations within the game. Meanwhile, Ellen McLain provides a good voice line to showcase the personality and character of Glados. The dialogue and voice acting immediately created a sense of whose a protagonist and antagonist in the simple story of hero vs. villain.

The co-op element of Portal 2 provides more levels to lengthen the game. These levels add some exciting fresh dynamics to each level because you have to cooperate with your team mate and depend on the other to complete levels. For instance, I had to stand on a button while my friend flew to the other side of the window to retrieve the block in order to complete the level.

Portal 2 is a good and challenging puzzle game that emphasises creativity and excels in the simplicity of telling a story. The story nicely builds to an excellent climax that feels like a satisfying conclusion to the game. The game features beautiful voice acting and some exceptional performances from Merchant and McLain and strongly delivers in the quality of the dialogue. I am new to the puzzle genre so playing Portal 2 felt fresh and different. There are some issues outlined above in the game, but nothing that detracts from the overall experience. At $19.99, I recommend it.

Rating: 8.5/10

- The simple story that ends with an excellent climax.
- Excellent voice acting.
- Very good dialogue.
- The challenging and increasingly complex puzzles.
- Length.

- Annoying glitches with the R feedback prompt in single player and frequent crashes via alt tabbing.

Im not the guy who likes puzzle games but maan, this game is really good.

The story is intresting, funny, fun. And it actually takes some real skill to finish !
The graphics loooks great too, and will pretty much run on everything. Played this on my old lapotp and it worked flawless.
The controls are great too and can also be played with a controller.

One thing that i really like about this game is the humour, cus you will actually laugh when you play this game. Such a fun game. If you are looking for a real masterpiece, just go and buy it! 8/10
