how do i make like levels? like xp and stuff. i already am making the map series. there will be 17 maps.
The ONLY thing you can do is use leader traits to give the person who is ahead an advantage. There is no way to add EXP into Halo, Halo is not an RPG.
wow you guys are so helpful/sarcasam. what i was going to do was i would whatch videos of my friends killing monsters(and thay would have grav lifts you would should.) then ill give em xp
Just a thought, maybe you could do like boss fights? using VIP proximity traits or something? So like it'd be similar to a group fighting the troll guy in the Deadmines, but if they spread out too much they'd die. EDIT: You are not very smart, judging by your post you made just now. There is no way to give players anything near "EXP" in Halo. You can keep track in your head if you really, really, want to, but the way you have it worded, you are asking if you can add it using game options.
You should rework your idea into a battleground or arena PvP. The world won't exactly work like you want.
I will check some gametype options this weekend but so far here is all I can recommend, perhaps you can do it bu either giving all players high health but low shields with strong shield vampirism and boss monsters (other players acting the part I would assume) overshields. That way when you kill a boss monster (unless you were terrible and almost died) you would gain their shields. However, to be anymore specific in what you should do I would need to know what are you going to do for opponents?
