Soon the principle of portal: (Who knows, that may skip here)
it looks like a first-person shooter, but it's actually not. the only weapon that you have to play in this is, who knew their own. without thinking you can not get very far in Portal 1 & 2. Violence in the sense is in these games is not an option and not really possible. you get at the beginning of the so-called "portal gun". thus it is possible to shoot a maximum of two portals on the walls. always applies: what goes in A portal that comes with porch addition and B reversed. the same applies to physical forces: what quickly comes in at Potral A, also comes just as fast at Portal B back out and vice versa. However, it is not to produce at all possible surfaces portals (eg. glass, liquids or uneven surfaces). The levels are usually designed so that the players have to think about how he can exploit features of portal to reach the exit. Thus it is necessary in most cases proceed very cautiously, because stupidity is punished ... often with the death.
Portal 2 is now what many have gewunschen ... it's like portal 1 only, longer, more sophisticated, graphical quality and especially longer;)!
but Portal 2 offers even more. In addition to new ideas like the "special fluid" was launched and the online live "co-op" into. in the latter case you have to (online) Couple in cooperation in order to resolve the levels work together. This is not only fun, but also provides an ingenious fun / extension for single-player mode.
graphically Portal 2 has been significantly improved. Although it is not a milestone, but the graph corresponds to the typical valve Quality: high quality, practically-oriented (also runs on older hardware), perfect design and 1A atmosphere.
The story is virtually the same as in Portal 1 and linked seamlessly to those from the previous more or less. however makes valve (as I find a totally cool way) no great secret of the story, but it is always the journey is the reward.
the levels in Portal 2 are even greater, but also (thankfully) more difficult. To think is the motto here, and it is quite normal if after one hour playing time smokes the pear. However, you also have to be a genius to be able to solve the levels. sooner or later sure everyone finds the exit.
the illustration of Portal 2 is just one thing: awesome! playing through vast areas of a scientific system. this seems to have been forgotten for quite some time. repeatedly breaks something together or not, or only partially functioning. Plants have already started their roots to strike, and of people far and wide no track. everything is controlled by a crazed artificial intelligence, what a joy it obviously has to chase people through the test chambers and to play with them. because nothing seems to be more of interest to you, as a biochemical brain and its unpredictable problem-solving strategies (the player).
Conclusion:
Portal 2 is just great! who could guide 1, is love Portal 2. and who has not played Portal 1, can confidently grab equal to Portal 2. if the gameplay of a portal (see above) responds, then you should seriously consider buying to definitely consider ... it might like! Portal 2 (1 & 2) is a game in which people with good spatial imagination, and pronounced linked / logical thinking, coming fully and entirely on their cost.
note:
the here some installation on Steam criticize so sharply, and therefore give a bad review, I find completely ridiculous. do you do that just so ... so what? by updates & co one is characterized at least immmer stood up to date and need to worry about anything. that the server in the first days are overloaded somewhat after the appearance, is really nothing new ... Oh My
Apart from this, an offline installation without steam quite possible ... simply turn off the Internet and insert dvd ... where is problem?
