Every gamemode would massively benefit from having an alternate mode.
It would be nice to essentially double gamemodes on the hive simply by adding subgamemodes, similar to skywars and skywars kits. Personally, I think this would bring many players back to the hive to try out the alternate way to play their favorite gamemode.
Here are my ideas on potential alternate gamemodes (this section may be long and boring lol):
(In order of me remembering gamemodes)
Skywars- Skywars kits. Not much to say here. I think if this idea is considered, sky-kits needs an update (like adding a few more kits.)
Bedwars- Treasure Wars/Rush Mode. This is going to be controversial, so please leave only constructive criticism in the discussion and not toxicity. The main complaint about Bedwars being on the hive is that the pacing is slower than Treasure Wars was. This could be solved by simply adding Treasure Wars as an alternate gamemode, or by adding an alternate “Rush Mode” where items are cheaper, delivering the faster pace people are upset about. Before you say that someone has already suggested this, I had the idea originally.
Just Build- Alpha Build. This would likely be the least played since extended time sort of functions as an alternate gamemode already, but imagine how creative players could potentially get with a limited block palette, forcing them to make creations that make you say “oh, that’s a clever way to make a [Build]”.
Block Drop- Nemo Slap Drop. Players spawn with 3 Leaps, 2 Knockback Nemos, and 1 Knockback Dory. Mystery loot is also changed to favor Knockback Nemos/Leaps. This would make players think twice about getting too close to everyone, creating more depth of game. Do you go to knock people off, or should you play it safe? (Also, nemo fights imo are really fun.)
Deathrun- Death Parkour. Honestly, I didn’t know how I’d think of this, Gravity, Groundwars, Hide and Seek, or Block Party, but my concept of this gamemode is for the courses turned into parkour courses by largely removing blocks and shortening the maps. There would still be traps of course, but the game would be based more on parkour skill rather than death avoiding skill.
Gravity- Gravity Teams. (I am grasping at straws 
) Pretty self explanatory, Average both (or all) team members’ times, fastest adjusted time wins. This is one of my weaker ideas, if anyone has a better suggestion, please tell me lol
Survival Games- OP/Basic Mode. Players can play a gamemode with stronger or weaker items, which grants them more ways to play. Do you like your fights longer, allowing for comebacks, or would you rather play a game where every hit matters? Personally, I think normal SG perfectly strikes a balance in the middle of these two, especially at the end during deathmatch.
Capture The Flag- CTF Kits. Okay, I admit that I stole this idea from Sky-Kits, but I think that CTF Kits would actually make sense. Players could choose kits that grant them explosive powers, better range, or stronger weapons. (I don’t have any specific kit ideas, if you take the time to read this, please suggest some <3) This lets players take specific roles on a team, and it would promote more teamwork in a game that, in my opinion, doesn’t use enough teamwork. Does your team need another archer holding down the fort, or would it make more sense to play a more offensive role? The shop would be for purchasing kit-specific bonuses rather than generalist items in this mode, since it’s not my vision for an archer to be rocking full diamond.
The Bridge- I don’t actually think this gamemode needs an alternate gamemode. The Bridge is a gamemode that lends itself to 1v1s, and I think adding an alternate mode would sort of defeat that originally intended purpose by making it wackier than it needs to be.
Block Party- Chaos Mode. Chaos mode would feature Knockback Boomboxes, Knockback Nemos (PvP items are only on before blocks dissappear.) Chaos mode would also have more than one “safe block” active (e.g purple and blue both wouldn’t dissappear) but the map wouldn’t be completely full at all times either. (e.g orange and red straight up wouldn’t exist some rounds.)
Ground Wars- Infinite Ammo Mode. While there’s nothing crazy added, having infinite ammo fundamentally changes the game. Maybe there could be powerups to disable someone’s shots?
Hide and Seek- Movement Mode (I can’t think of a better name). Both hiders and seekers now have energy. (whoa!) Leap is added, as well as ender pearls. Be warned though; for these consume a lot of energy. (Hiders have less energy than seekers, so they can’t infinitely run) Should you stay in a spot and risk dying, or would it be better to get out of there ASAP?
Murder Mystery- Multiple Murderers. While having multiple murderers doesn’t seem like it’d change much, the game not being over after only one murderer dies would change the game a lot. Also, it’s just FUN to be the murderer, and this would allow that to happen more times.
If you stayed to the end of this post, thank you so much. If you didn’t, thank you anyways. This is your reminder to keep all discussions civil and non toxic. If anyone has better suggestions, it’s greatly appreciated.
