There are already various Battle Royale games, the arma 3 mod, the battleground game, the H1Z1 game…
They are mega ultra super famous and an extreme amount of people play them.
At those games people fall from planes without weapons (unless you count being able to punch in PUGB as a weapon) and must find weapons and items spawned at random places.
There is a death area (that increase after time), like the book/movie and the last person (person of the surviving team or team) to survive is the winner.
The thing is, how islands of nyne, will survive or stand out against those super famous games?
Here I propose HUGE changes that will make the game stand out:
1-Keep the scifi, you will need it.
2-Instead of being humans in a armor pack, you are robots/androids. Change your background story to fit this, maybe a new TV sport where humanoid robots battle for survival in a battle royale setting, maybe humans died and there are only robots now (and for some reason they do battle royale stuff), maybe some company do battle royale to test the androids they built…
3-Those androids have batteries and they can run out of battery.
4-The robots/androids fall from a plane or whatever like the other games.
5-There random robot addons/packs spawn at random places, you can change your arm for a minigun, or keep your hand and use hand weapons, or find other robots addons you can swap with your current addons…
5.1-Players can still punch others, if they don’t have guns
And here is one huge change that make your game different from others.
6-There is NO death zone, planes keep dropping batteries at random places and you must get those batteries if you want to survive, if you don’t get them, you will run out of battery and you will die.
So instead of avoiding the death zone to survive, you pick stuff that will be at random places (batteries) to survive.
6.1-If wanted you can even make that guns use some amount of battery, and if you are more packed you use more battery, or you can make it a optional mode, or if you hate this idea 6.1 you just don’t include it.
And those are the idea, not only this will make your game stand out against others battle royale games, but bring a fresh idea to battle royale (idea 6).
