He will be writing and illustrating Deathstroke and plotting The Savage Hawkman and Grifter.
Liefeld has been writing and illustrating the recently cancelled Hawk and Dove.
He will be pitting Deathstroke against the bounty hunter Lobo in his run, while Hawkman will take centre stage in a gladiatorial arena.
The Daemonite invasion will be coming to a head in Grifter, with the promise of a newly reimagined WildStorm character debuting in the title.
"It's great to have Rob contributing to DC Comics - The New 52 in such a major way," Eddie Berganza, DC Entertainment executive editor told The Source.
"Rob's always been seen as edgy, both within the comic book industry and by his fans. That's a great vibe to bring to these particular books. We really want to push boundaries, and Rob's the guy to do it."
It is unclear as to whether the current writers will all be displaced by Liefeld or will simply collaborate with him on the series.
Liefeld will be joining the three titles from their ninth issues.
