I think a cool minigame that Meep would be the first to add would be gun game from COD (Call Of Duty). If you don't know what gun game is, read the following paragraph.
Imagine spawning in the middle of a random map with a pistol and players around you trying to kill you. You turn right and kill a person and your pistol disappears and is replaced with a sub machine gun. Then you turn around and get knifed and get dropped one gun rank, and the pistol re appears. So there is over 20 gun ranks and everyt time you kill someone your gun rank goes up and your gun changes. The past gun rank is the hardest to get and if you kill someone with it you win. Now if you are killed by a regular player with their gun your rank will not drop. Your rank only drops when you are stabbed in the back.
Now how I thought this could be original to Meep is that we have all leather armor, iron swords, a power 1 bow, and one fire charge (the fire charge is a one hit kill). The gun ranks would alternate between receiving different swords and/or receiving a potion effect that can help or hurt you. First one to get to 21 gun ranks would win. The ranks wouldn't have to be randomized but you could pair the swords with potion effects to balance the kits.
I'll list some kit ideas, and the maps can be made by the community and/or the architects, but a community challenge would be best.
Gun rank 1 (starting class; can not drop lower then this): Full leather armor iron sword (no enchants) speed I Flint and steel on 1 durability (equivalent of a knife in COD).
Gun rank 2: leather armor prot I stone sword and absorption flint and steel (same as the rest)
Gun rank 3: Iron armor and a power 1 bow with 16 arrows same ole flint and steel
Gun rank 4: leather armor prot 4 wooden sword and regen 1 same ole flint and steel
Gun rank 5: no armor Diamond sword (no enchants) strength 1 same ole flint and steel
Gun rank 6: Iron armor Power II bow poison 1 for 30 seconds same ole flint and steel
Gun rank 7: leather armor fire protection 4 five fire charges and speed II same ole flint and steel
Gun rank 8: iron armor prot 2 stone sword and blindness same ole flint and steel
That was some idea of gun ranks, if you have a rank idea post below and give feedback.
