''[[https://www.fanfiction.net/s/6718220/1/Hammerhand Hammerhand]]'', and its sequel ''[[https://www.fanfiction.net/s/6731833/1/Angels-of-the-Storm Angels of the Storm]]'', are a pair of ''Franchsie/MassEffect''[=/=]''[[TabletopGame/{{Warhammer40000}} Warhammer 40K]]'' crossovers by [[https://www.fanfiction.net/u/1828459/Colonel-Mustard1990 Colonel-Mustard1990]]. The premise is that a squad of Space Marines takes the place Shepard would normally hold in the games, and how their AbsoluteXenophobe outlook and experience in the CrapsackWorld of 40K would stand up in a universe like ''Mass Effect''.

When their ship comes under attack by Orks, [[TheCaptain Captain Malleus Scandarum]] and his command squad are flung through time and space after their Thunderhawk is hit by a Shokk Attack Gun. Coming out over a sparsely populated world, one with technology and aliens that the Marines have never encountered before, Malleus and his men try to adjust until the planet is attacked by the Collectors. The Space Marines fight off the aliens, drawing the attention of the Illusive Man...
