Sup everyone, I’m making this thread to share my ideas for some gametypes and playlists. So here they be homebre!
Gametypes
Infection Additions
There’s now an option that is called instant infection that makes it so that when you get infected you don’t die or respawn but instead become instantly infected on the spot making large groups very vulnerable.
Flood Invasion
Flood is now a cross between infection and invasion like Dead Space 2 Multiplayer or Left 4 Dead Versus where the survivors must reach a objective to activate something to move forward. Survivors cannot be infected, only killed for about 10 to 30 seconds then they respawn. There isn’t just Flood spartan forms now instead it’s all sorts of forms from a Swarm of Infection Forms to the Juggernaut, there’s also completely new forms that do things like fly, burrow into the ground, and shoot spikes into its enemies to mark it for its teammates.
Base Defense
Base defense is where there are two main bases on each side of the map, more bases can be built but if you loose the main bases you are put at a severe disadvantage. There’s a commander on each team that can teleport everyone to the main base in case there is an emergency, this commander can also give out orders such as repair, defend, attack, heal, fortify, and resupply. You win when all of the opposite teams bases are destroyed.
The things you can build in Base Defense are…
Store (here you can buy weapons and upgrades. on the other side of the store is a small area on the floor you can step onto which will auto refill your ammo for X amount of credits)
Teleporter (Use the teleporter to get around from one base to the next but to teleport there needs to be a teleporter you’re teleporting to)
Vehicle Station (Use this to purchase vehicles such as the Warthog or Mongoose)
Base Radar (Alerts the commander when an enemy is in a base, it only notifies you if you’re in the area of the base)
Double Gametypes
Double Gametypes are when someone combines two gametypes together to make one, for example I would make Oddball Slayer where when you pick up the oddball your team gets double the points putting the team with the oddball at a severe advantage.
Oddball Changes
The Ball itself now changes colors depending on who holds it, so if I’m holding it the skull and light around it will be Blue while the metal incasing the ball will be yellow.
Dominion Changes
Spend points you’ve earned to buy weapons and vehicles at weapon and vehicle stations, there are no longer ordnance drops when the base resupplies but instead the store get’s resuplied with more weapons and vehicles.
Dominion could probably get replaced by the whole base defense thing 
Invasion Additions
Invasion returns with the good 'ole Green Vs Purple teams and this time with more objectives such as killing a high value target, destroying a certain thing such as an AA gun or engine, and escorting a VIP to a door to enter a code only the VIP knows.
Overall Additions
There’s an option to add knockback which makes it so when you’re shot or you shoot you get knocked back X amount of feet.
There’s an option to link an object, weapon, vehicle, or anything in forge to spawn when you complete an objective like capturing a territory or killing X amount of enemies in Slayer.
There’s no more vehicle stations that spawn certain vehicles, instead it’s just Small, Medium, and Large vehicle stations that can spawn certain vehicles depending on what you choose for those stations to spawn.
