So since Halo 5 is in need of some new gametypes here are a few easy and basic ideas I have for it.
-Swat with more weapon varieties such as BR and Magnum in the same game, Light rifle Swat, or Carbine Swat
-Fiesta (just respawn with random weapons)
-Paintball (plasma pistols only with insta-kill)
-Infection
-Juggernaut (one player is the juggernaut and has overshields and the rest of the players have to try kill the juggernaut and the player that does becomes the new juggernaut)
-Regicide (just like Juggernaut except that the juggernaut is the player with the highest score)
What are some other ideas that could be easily added to Halo 5 that you want to see.
