At last, you can now kill and be killed in multiplayer on Minecraft-servers. Hopefully this will mean that you'll soon be able to play custom games like Capture the Flag, or just play some regular Survival with your friends.
Personally I'm the most excited about finally being able to explore, craft and hunt down those damned creepers with my friends. I really enjoy Survival the most, building huge stuff is also fun, but it doesn't cater to me in the same way.
I might throw up a server that anyone may join if there's any interest.
Thanks for reading!
