Yes, this game is dated. Yes, the graphics aren't up to today's standards. Yes, the gameplay loop is very repetitive. Do I care? No. Boom. EDIT- Goated Devs. Brought the game up to today's standards and I love it.

One of the highest achievements in video game art. Horrifying in its simple abstraction. Haunting and tense. The recent 20th anniversary update brings a lot of improvements for modern setups and resolutions.

When they basically remastered the game, they kept the legacy version available. That's all you really need to know about these people.

Nothing better for a quick brain-cleanse, going back years.

(guys, yes, i like the damn game.) There are a couple of reasons why you might not want to play DEFCON: - It's analog horror, in the purest form. The world dies! - The music is terrifying. (terrifyingly well designed, too.) - The skill curve faintly reminds me of an exponent. Outside of this, you have just about every reason to be playing DEFCON, if you wanted to simulate genuine insanity, along with a side of cold fear. Something about this game reminds you about why dangerous things are... dangerous.
