This level is impossible, GlaDoS, the omnipotent voice, says. Make no attempt to solve it. Just your average day in Aperture Labs. From the first level, where a voice politely tells you that the toilet WILL, in fact, take your crap, to the last, a puzzle packed, suprise filled boss fight, Portal supplies fun behind every one of the titular inter-dimensional gates. The story: You wake up from stasis in a glass case with no memories of your life before. An AI puts you through a couple tests, and then tries to throw you into an incinerator. you survive, and decide you need to blow her up. (Plotline: 4/5) Once you get past the bizarre plot, we come to the gameplay. I would describe the game as a FPP (First Person Puzzler). The Portal gun is the Best Gun Ever. It can shoot two corresponding portals. If you shoot two portals, you can drop objects or walk into one and come out the other. This can be used to drop objects on turrets, get to otherwise unreachable places, and put Turrets in those otherwise unreachable places. Its like a 3d platformer with teleportation! (Gameplay: 5/5) Now we come to the behind-the-scenes things: Graphics, Physics (graphics+physics= Engine), and Details. The graphics and physics come from their home built engine, the Source Engine. That engine has powered games like Half Life 2 and Team Fortress 2. Trust me. the graphics and physics are amazing. Valve doesn’t disappoint. (Engine: 5/5) As for the details, they are GREAT! From the toilet telling you it will take your crap to the frosted windows in some of the test chambers, they will make you wonder how long it took to put them in. Its all about the details. (Details: 5/5)

TOTAL: 19/20
