Development Milestones is progression that unlocks new operators and Hot-Zones. This guide on How To Increase Development Milestones In Tom Clancy’s Rainbow Six Extraction will tell you how you can increase your Development Milestone Rank so you can level up fast, unlock new content, and get to taking down the infection.
There are three main areas of progress in Rainbow Six Extraction. Operator, Tech, and Development. Operators earn experience points through completing missions, unlocking new tech and ability upgrades. While Development Milestones are increased by completing very specific objectives laid out for each of the Hot-Zones you will encounter. The first and only area you have access to at the start of the game is New York, so you need to complete the New York Studies Objectives.
How To Increase Development Milestones
From the main menu go to Progression and you can see your current Development Milestone level. Each new level unlocks new advancements, that you can find on this screen. If you want to increase your Development Milestone level, head to the Play tab.
From the Play Tab, choose any Hot-Zone. New York is the only one unlocked by default. Don’t hit Quick Play or choose a Hot-Zone, instead select Studies. Here you can view all of the objectives for current, future, and past Development Milestone levels. You need to complete each individual objective. For example, the first set of Studies for New York City are called Intro to Nests, with the following objective: Look Up (Ping Nests on walls or ceilings), Nest Popper (Kill Nests), and Nest Removal (Kill Dormant Nests). Each objective rewards you with Development Milestones experience points. Continue to follow these objectives as you progress to rank up fast.
