Best 4Player PS4 games

maxious

me and my boys are doing a gaming weekend at the EXP leisure venue in London. Their are a lot of things going on from board games to VR.
But I'm working with a small network of 4 PS4 consoles. and I'm wondering what would be the best games to put on these.
I'm making a list of games to put on them that are quick to play and good multiplayer games upto 4 players on its own network.
games can be Competitive, Co-Op or PVP.  I'm looking for games that not only put people in a fight against each other but also maybe something that's a little exploration. I would put in minecraft but don't have time to build a server for it.
so far i've thought of
Over Watch
Infinite warfare,
Bloody Zombies
Rocket League.
Mortal Kombat XL (Yea I know its only 2 players but I need options)
Gauntlet: Slayer edition.

any one else got any ideas I can use for the PS4?

Doom? Also has a map editor.

Doom. BFG edition I think. but I'm not to sure if that's PS3 rather than PS4. would be good if PS4 has access to the old school version. if their is ill certainly recomand that. I'm sure their would be a lot of retro gamers there who would love to play the classics on modern equipment
