I blew a full weekend's worth of gaming on the recent Call of Duty: WWII multiplayer beta, and I have to agree that it was "pretty damn fun." I also agree that cheaters are the worst, although that's mostly a matter of principle: Aside from one bonehead single-handedly holding the bridge in a War mode match, I didn't encounter substantial amounts of skulduggery. 

Nonetheless, Sledgehammer said in a post-beta update that it's aware of problems with hackers, and has plans to deal with them.
