Portal series (InstanceTopic, 14)

<[#ontology [kind topic] [cats Series]]>
The '''Portal series''' is a series of [[video game]]s in which you must ''think with [[portal]]s''. The apparent [[reward]] for the original game is [[delicious cake]], but as well know, ''the cake is a lie''.

The original game was a [[spin-off]] of [[Half-Life]]. There was then a [[indie|fan-made]] [[2D]] Portal game made in [[Adobe Flash]] which was surprisingly faithful to the original [[physics]]. Most recently, we've seen an [[official]] [[sequel]], aptly titled ''Portal 2'', which vastly expanded [[gameplay]] and [[storyline]] alike.

== Portal puzzles ==
A ''portal puzzle'' is a thread commonly posted on [[imageboard]]s where people try to solve a [[puzzle]] using portals. They are usually subtle and vague, to encourage [[humor]].
