I didn't really like Crysis that much but this Back to the Future mod makes me want to go play it again. As you can see from the video, this mod is extremely detailed and actually allows the player to time travel. If you want to give it a try, you can get it off crymod.com.

This is exactly what you are supposed to do when you have a bunch of excess tinfoil. Pretend you’re from the future.

On a related note: tin foil hats amplify alien’s ability to read your mind.

There’s a t-shirt for the Let’s Say You’ve Gone Back In Time poster. But why is it brown.

Get it from topatoco for $18.

You better bring this with you. But I guess it depends how far you get sent back. If you’re sent too far back, then you’re screwed. You can probably invent fire and the wheel but you wont get crap from that. If you only get sent back a few hours, you’re also screwed. Unless you did something within that few hours that so super horrible that you want to reverse, then I guess it wont be so horrible.
