Trip to Apenture Science has never been such a great laugh.
The Portal 1 gameplay involves creating 2 portals to navigate around the obstacles, Portal 2 in the other hand does the same thing, only with different enviroments and at later stages introduce gel which "_____" also serves as a method of getting from point A to point B. Certain section of the game requires players to attached 8x optics and ironlungs perks loadout "only available for FPSgamers"
The gameplay Its not addictive as compared to Trails HD or as mysterious as Limbo which both priced at $10. What Portal 2 fancies are the top quality voice acting and script which was made from scratch since Portal 1 story was NEARLY non existence. Portal 2 however does give players some insides on whats happen in Apenture Science and anything outside is "BLANK". It does sums up for a potential sequel.
Valves uses the latest Valve engine which is nothing much of an Eye candy, but it still presentable and playable.
Coop allows players to play with a friend controlling 2 robots to solve an all new puzzles created by valve giving some extra 3hrs of gameplay. Also theres user created maps which will help to extend portal 2 community although most of them i tried arent as good as "valves".
Conclusion, its a family game where parents would spend 1-2hrs with their kids playing Coop (console). The most puzzles are not challenging slightly easier than Portal 1, just trial and error. Highly recommend a rental for consoles especially for local coop option where parent/kids or bf/gf would spend time communicating and solving puzzles is extremely enjoyable. If a lone gamer, check out the above 2 titles.
