Eurojank in the best possible way, Infra has some truly unique ideas. Its puzzles are all set in the context of the real world - repairing switch boxes, setting up a water treatment plant, and other engineering problems are seamlessly integrated into the levels. A pretty interesting backstory of corporate corruption and greed underlies these puzzles, though it's perhaps a bit overwritten near its end. It also commits the dire sin of being about 2 hours too long.

Still, I haven't played anything like this before and probably won't again. Despite my minor complaints, you can tell the developers really gave a shit about putting something new into the world. Glad the Euros still have their magic Source engine touch.
