I belive that people should be able to spawn NPC's like marines, spartans, firebats, grunts, elites, some flood units, ect, (most covenant and UNSC , and few flood units included) Im not sure, but I might want to have AI units like spartans, elites that use armor abillities and, may have a map scanning system where it checks some or ALL possible paths and points of interest (such as weapons like shotguns and rockets or vehicles like scorpions or wraiths) That's all I have to say really but if anyone has any comments or ideas, you are free to share.
