Minekill
So, this is how the game would work:
It's similar to Hunger Games, but underground. You spawn in a small mineshaft around a massive cube full of classic materials needed, wood, diamonds, coal, stone etc. You start off with wooden tools of each type, leather armour and wooden weapons. You have 10-15 minutes to mine and collect the materials that you will need, then after you have collected all the materials you need, or the time runs out pathways will begin to form, (or an alternative for this could be a tool which can break blocks in a 3x3 area instantly to make pathways) This is the killing time, you will use the pick to find other players, but you can't see their username or their health. Once people start to die less and less people will be in the game and it will be harder to find people, so the cube will begin to shrink, obviously you can't see it shrinking so you will be alerted in chat when it is getting close to you saying "The cube border is getting close." This then gives you time to get away, this will also make it easier for the players to then find each other. Once there is only one player left they win

Perks / Upgrades:
- You can upgrade each tool INDIVIDUALLY to a stone tool, then to efficiency 1, then 2 and so on. You can NOT upgrade the weapon as you need to find the materials for that
- You can purchase speed perks from the shop as well, and then upgrade them with coins you get.
- During a game, you will get coins every 30 seconds you survive, and for every kill you get.
- You are able to spawn with a crafting table, but in the shop you can possible buy "Mine upgrades" which allows you to choose between a Furnace, Enchantment table, Anvil, Brewing stand etc.
- You can purchase mob eggs (or spawners) which you can place in your mine (spawners could have a seperate room) this allows you to get food, materials for a brewing stand etc. You will start with the usual Cow (For leather and food) Chicken (for feathers and food) and a Spider (for string)
- You can purchase a wolf pet from the store as well to assist you in battle.
Map Layouts:
As the maps will be underground you could have themes such as:
Under The Sea
Mineshaft
Cavern
Deep Depths
As well as this all maps will have around 12-24 small rooms bordering the cube depending on how many players are needed.
The cube will be something like 100-150 width, length and height.
I hope you all enjoy this idea!
