Assault: Team A is tasked with defending an Island fortress with a small town inside. Team B will land on the beaches in waves of 30 every 1-2 minutes and attempt to capture a point within the fortress. Team B must blow a hole in the fortress wall, fight your way through the town, and capture the point to win. Team A will have limited reinforcements, but many tactical advantages such as high ground, superior cover, turrets, etc. Team B will have unlimited Reinforcements, but they will have to get across the beach D-day style. If Team A holds out for a set amount of time, then they win.
Capture the Flag: Two teams must attempt to bring the other team's flag to their own base while defending their own.
Intel grab: Two teams fight to capture a briefcase in the middle of the map, and return it to their own base.
Demolition: Each team must escort a team of bomb experts to the other team's base and protect them while they arm the bomb. Remember to defend your own base too.
Convoy: One team escorts a convoy of command vehicles and trucks across a map to win. The other team must completely destroy the convoy before it reaches the way-point.
VIP rescue: Team A must fight to locate a bunch of VIPs and get them to the extraction point to win. Team B must do whatever it takes to keep the hostages safe and in their hands.
Zombies
Survival: Team up with other players to find food, weapons, and kill any zombies that come your way. You get points for each day you survive and the zombies you kill. you are a civilian, so you will have few weapons in the beginning of the game. During daytime, there will be fewer zombies about, so use this time to forage and explore. stealth and hiding are sometimes better than shooting at everything you see.
Defend the Quarantine point: You and a band of soldiers must defend a fort full of civilians from zombies as long as you can. you get points for the amount of waves you survive and zombies you kill. you lose if all soldiers are dead, or if all civilians are dead.
Rescue: You and several others must survive a few days from zombies until a chopper lands somewhere on the map. you must then fight your way to the chopper to get out of there to win.
Rescue Ultimate: A twist to the original Rescue, where there are 20 players ( can be AI too) scattered around the map. This time however, the chopper can only take 4 survivors. So find and choose your alliances, eliminate the competition, survive the zombies, and be careful who you trust.
Containment: A team of heavily armed soldiers must completely cleanse a city of zombies. To make things worse, every single zombie knows where you are, so they will come at you constantly.
Convoy (Zombies): Your Team must escort a convoy of civilians to a safe zone while protecting it from attacking zombies. As you get closer to you destination, the attacks will intensify. Make sure you stay with the convoy; being left behind will be certain death.
Any other Ideas?
. The other option was having the spawn point moving progressively closer; once team B established a foothold on the beach, soldiers would then spawn directly on the beach, then at the fortress walls, so on.
