Crossovers are a funny thing. Two media properties smashed together in an attempt to get the fanbases of both reading, and some passerby rubberneckers as well.

Usually it's advisable to tell people that such a crossover is happening though. Like retailers. Or retailers. Or, I don't know, the news/rumour website that you actually own.

Well, better late than never. Right, from here on in, this is a major, last page reveal for tomorrow's Mercury Heat #7, the sci-fi police procedural comic book set on Mercury, by Kieron Gillen and Nahuel Lopez.

If you were planning to buy the comic anyway, stop now and don't spoil yourself.

If you were planning to read it in the trade… your call. Odds are you'll hear about it one way or another before then.

If your interest is now piqued and you are currently thinking about buying it tomorrow, stop now as well.

Okay. Here we go.

Our hero encounters a rather abandoned base… with people smeared across the insides…

And then finds those responsible.

That's right folks. We have a Mercury Heat/Crossed crossover.
