I thought of this idea while playing a custom game full of AI. So it's technically a fps, so there will be different arrows. Red suction cups/slows them down, green arrows/knocks them out but regeneration speed is 5 seconds, cupids arrow/make them fall in love for 5 seconds, and harpoon/causes an oil spill (same as banana peels) different characters have different abilities (it includes for the player shooting and for the zombies) example: Nemo will get you 5 more arrows. There will be 2 options, level mode or survival. Survival mode has unlimited arrows, level mode will have limited arrows depending on how many zombies there will be. You can also shoot for power-ups, they will spawn randomly but some items will be more rare to spawn for example: spinach makes the arrows stronger and bombs wipe out the entire army. Players can choose which side they want to be on, maximum players on shooting side is 2. Zombies can dodge multiple times. In survival mode, players can grab power-ups before the shooter can get to them. That's my idea, give me some more ideas or tell me if something doesn't make sense
