Aliens #2 (2009)

A strange, abandoned city of impossible scale lies ready to give up its secrets, but at what cost? Jealously guarded by a half-mad group of planetary prospectors, the labyrinthine necropolis may be a treasure trove of incomparable wealth, or a funeral complex with no exit, as an archaeological team from Earth discovers too late. But these off-planet interlopers soon become the least of the prospectors' worries, as their priceless possession offers up a monstrous surprise of murderous beasts from the darkest abyssal nightmare . . . and the prospectors only hope may lie in the unmarked graves of those they themselves betrayed.
