I'm not a noob forger. I've forged my fair share of maps, but like most other forgers, I am clueless to Invasion forge style. So for my map in development, I'm making it highly campaign-like (and I've done my research from looking over all the top invasion maps and I can assure you this is the most linear campaign gameplay you're going to get), but I'd prefer to have more than three phases to work with. All the Invasion gametypes I've played have only ever had three phases, with an alpha and beta capture zone for all capturing phases. Is this mandated or just an effective preference?
Not that forge-fancied myself, but no i believe the limit is three. In all my times i've played custom invasion maps i've only seen 3 total.
The two territories per phase for the first two phases followed by capturing the core is just a standard way of doing it, although people commonly use assault for the second phase. You can do almost anything you want within the limits of assault, territories, and capture the core for these three phases, however you are limited to three phases. There is no way to change that unless Bungie releases an updated gametype. It is unlikely you could make an invasion map with more than three phases yet remain within the budget anyways. You can always make a map pack with sequential maps to essentially increase the number of phases.
This is what I was considering. Now that I think about it, even if I DID have the budget/gametype to go six phases, it would take too long. Although I am a bit disappointed.. Is there a way to adjust the spawns so that they change in between phases, making appearance of multiple phases?
i'm pretty sure you can go up to 5 phases, you can set it in the game type editor, not the forge editor.
Spawns in invasion are different than other spawns, and they are definitely able to be moved between phases. It wold take too long to explain here, but look up how they work, because just having spawn points on the map wont do anything. In fact, you don't even need spawn points, it's all about zones.
Random question here, though id post it in this thread whilst an invasion convo is taking place. Is it possible to have a neutral invasion so to speak, by that i mean both teams attacking neutral goals at the same time with the winner being decided by points total at the end?
