HCF : HardCore Faction is a game on minecraft, like a faction, but everyweek it got reset, if you die in that serv, you got ban during something like 1 hour ( it depends of the server btw ). Thats very similar to a faction but you cant raid with tnt the people's base, like supose than im the only one in my faction, if i die one time my DTR (Death to raidable) go to 0.1 (we start with 1.1 if alone in the faction) if i die again, im going to be raidable, like people will be able to come in my base, take everything in the chest, break the base, EVERYTHING, thats why thats hard, but if your DTR is positiv, nobody can come in, or break so thats why you can do your base near other base without panic. On a faction server you will be able to raid the base with tnt (If you are skilled of course). On that type of server (most english) there is a lot of trapper, like you can run for your life and fall in a falling trap and die in, in a few seconds xD, thats why thats funny
IM NOT THE BEST TO EXPLAIN HOW IT FULLY WORK, but come try ittttt a good server is vipermc ( play.vipermc.net ) a little bit pay to win, so if you rather not pay to win there is CavePvP (cavepvp.org)
