Material I

Material I is a progression achievement awarded when the player first obtains Titanium; it functions as an in-game milestone within Mindustry's achievement/progression system, marking the player’s initial acquisition of the Titanium resource. The achievement itself does not produce items or change gameplay mechanics but records advancement toward overall completion and achievement tracking, serving as an indicator of early-resource progression and unlocking any achievement-based statistics or meta-rewards tied to milestone attainment.
