Puzzled is a Half-Life mod about solving puzzles. There is very little combat and all of it can be avoided with a little thought.
Just a small map in the new Puzzled 1.2 Expansion, it has more combat then any of the other Puzzled maps to add a little more challenge.
So far the map is setup for for Hard and Easy mode, certain items change and a new Cloaked Alien Grunt spawns in when you choose hard mode.
