Party Harder With a Buddy in Party Hard
I guess ever since Hotline Miami really hit it big, devs have been chasing that action/twitch/puzzle-y murder sim vibe that it had going for it. Enter newcomer Party Hard, which tasks you with killing everyone at a party (because it's 3 am and they can't keep it down) as sneakily as possible. The title got an update this week which now lets you achieve this task with a local co-op buddy.
