Close!

I'll tell you straight up Resident Evil Mercenaries really isn't worth your money, the game gets stale pretty quickly and should have stayed as a mini game in the main series. I don't know much about the other game but people seem to like it so out the two, Harmoknight.

Last time I played Mercenaries I couldn't find anyone online...
If you get it, let me know...

Mercenaries is a great game IMO. I still have my copy around here, so if you buy the game, tell us.

Meh I'm going to go with Harmoknight because I'm not that much of RE fan to begin with.

I'd say Harmoknight over Mercenaries but I'd also say any other game over Mercenaries. Now RE: Revelations is a different story. That's a great game. Mercenaries is an overpriced mini game.

If you are getting Resident Evil via eShop, get Revelations, the overall game and multiplayer on that is better then what you'd get with Mercenaries. So between the two Harmoknight,

Not to mention, the HD version will have a more more improve online.
