If you've played Portal 1, the core gameplay of Portal 2 does not have any significant change. Player becomes Chell, a headstrong girl (and also like his taciturn Gordon Freeman), using the gun called the Portal gun to solve the puzzles in the game screen, namely the attempt to open the door Exit . A special feature of the portal is the gateway space gun yellow / green on white walls. With two ports this space, Chell can enter and exit a port in another port, whether the two white walls in How far did.
However, had the puzzle must be challenges. Through each screen, players are introduced to add a new function, as well as its challenges. With increasing difficulty, from very simple when new players first met such a spring board, until quite complicated when it comes to combining the skills the player from the previous game screen in the next puzzle follow. Portal 2 introduces many new elements completely than part 1, as Hard-light bridge to bridge players combined with the Portal gun to be bridged; the powerful spring plank plate Aerial fate; and most interesting is the 3-gel blue, orange and white with 3 different functions.
