Basically the last and Next-Gen Upgrade of DOA 5 from DOA 5: Ultimate. So it's the same deal of any other fighting game expansion, 2 new two characters, re-balancing, new costumes, new dialog, and etc.
Only real interesting thing about DOA 5: LR is two things. First the game is on PC to fill the void of empty fighting game market on PC that people so desperately want (though apparently the game will a month delayed on PC). Second most interesting thing is that if you DOA 5: Ultimate on last-gen then DOA 5: Last Round will be a free upgrade for you by way of update. Good to see Tecmo-Koei aren't going to go completely out of their way to fuck you out of your money like other Fighting Game companies *cough*Capcom*cough* *Cough*ArcSystem Works*Cough* that's what the costume packs are for.
