343 has multiple other teams they need devs for.
Halo Infinite obviously makes the largest part though. With Slipspace they are clearly aiming for something super ambitious here.
- Halo 5 live-team
- Halo Wars 2 live-team
- Legacy team (Halo TMCC + all older Halo games)
Very true. But I'm assuming that of the 500 people there that 400 of them are on infinite. Maybe it's only 350 or so. But I only put down that they had 100 outsourced workers. That could be a massive lowball because we know the coalition has around 250 outsourced workers.
Obviously it's impossible to know how many people are on the game. Low ball number is probably 400 total people(including outsourced) highball number though is around 600.
Either way if infinite doesn't launch till holiday 2020 than it either has a massive budget, or it has one of the biggest budgets on a video game ever. 400 people over 5 years is about 250 million. 600 people is about 350 million. Either way it's probably the biggest budgeted game Microsoft has ever made.
