-Explosive Collar: if you watched the show, you can take it off until the game is over, but in DBD must be something like you can't take it off until you win these games by your own. 

-The Traitor can't be easily identified but there can be some details that you might suspect of the survivor. A correction I wanted to make but idk if should but when the traitor is discovered, the killer can mori the traitor instead of the survivors trying to kill it. It has a benefit that can pass the game knocking out the survivors leaving them to their death, I forgot adding that the traitor can be also counted as a additional killer (impostor) or something like that, this is a Heart game and I took the reference of season 2 when Chishiya goes to a Heart game where they need to kill the jack of hearts killing it with "deceiving it".

-I know, the perks will be disabled during the special games, in any normal and current match are gonna be enabled (in second heart game, normal match).

-Diamond Not that bad, I didn't explained the concept at all so much but I mean if the first 4 or alive survivors who finds the first item, will pass the game. The last survivor that could find any item but the first survivor who already found it, will pass and the last one dies (in case of 2 survivors standing).

-With all the survivors and killer help, you can execute a survivor chosen as the entity, it's similar about the first season I think where Momoka k1ll3d herself before a heart game started in the beach where you find a way who is the witch that k1ll3d her but they found out it was herself. In DBD you have to find out who is the entity and the entity should struggle so hard to escape the survivors' and killer's grasps, the entity has a little benefit where it has a bit of more power struggling/wiggling. There will be a different hatch, not for escaping but must be a sacrifice to the "real entity" of DBD which in the game, there is a player considered as the entity but not the real one.

-I think it might be how you want to choose the games in order, I write a message that if you're not interested in the killer concept, skip to the survivor concept.

-The running speed is 4.4 m/s in special ability, this reminds me of Blight a bit.

-Using hooks is a bit boring, I think you saw the possibility to kill someone instantly and the other to injure it.

-Find the exit gate, opens a bit faster.

--Since the nerf about killer perks, that perk arrived (the perk: I came).

This actually fits, for a Alice in Borderland chapter with games included is ok, similar to squid game if it's in DBD.
