mine may look stupid but here it is:

Normal endless survival but w/o hellhounds: A player should do a normal endless survival game but disable hellhounds.

Campless: You must do an endless survival game but never camp. You have to got it to a highest round possible

Duo/Trio/Squad: You must submit a run having 2, 3 or 4 people's in match and try to get as far as possible.

Perkless: You must reach the highest round without any perks.

Guns Speedrun: You must get all guns as fast as possible during the single game session.

PAPless run: You must get to the highest round without PAPing your guns.

Single game session run: You must reach the highest round during a single game session (no leaving), You also need a recording of everything (rip mods watching 73 hours video of some guy reaching round 213)

Well, That's all my ideas by now, leave yours below.

@1k_grindOfAberration Perkless and the Duo/Trio/Squad challenges sound good. Guns Speedrun might not be a big departure from the normal endless game, but PAPless Run could add a unique twist. The Single Game Session Run is crazy the thought of those hours on the leaderboard is both daunting and exciting.

@1k_grindOfAberration you do have some pretty good ideas

here's my list (i'm taking some of yours):

Round Speedruns: Speedrun to round 5, 15, 30, or 50 with 1-4 players. If no gamepass, all players must have footage recorded.

Campless: (does not require gamepasses to be disabled, all gameplay must be recorded)

No Perks: (does not require gamepasses to be disabled, all gameplay must be recorded)

No Power: (does not require gamepasses to be disabled, all gameplay must be recorded)

First Room (Gamepass): (Separated by solo, duo, trio, or squad)

More ideas: Got a "endless survival pack" As quick as possible. By "Endless Survival" Pack I mean:

PAP Raygun, Double Tap, Quick Revive, Juggernog

Teddy Speedrun: Get the Teddy bear from Mystery box as quick as possible.

Alright i ran out of ideas

teddy speedruns would be rng hell lmao

yeah that wouldn't even be fun
