Description

Black Mesλ, sometimes abbreviated as 'BM', is an organisation founded by the US Government with the sole purpose of researching and developing new technology, in order to aid the US and its allies. Our current projects range from inventing prototype energy weapons, to creating and testing teleportation devices. The latter undertaking has subsequently led us to discover a space between dimensions known as 'Xen'. As a result, we also study anomalous specimens collected from said border-world. ──────────────────────────────────────────────────────── Founded: [CLASSIFIED]/[CLASSIFIED]/195X Founded (IRL): 06/06/2020 Timezone (RP): 1995 ──────────────────────────────────────────────────────── Competitors: Aperture Science Allies: - Head Administrator: THEO34578 ──────────────────────────────────────────────────────── Game: https://www.roblox.com/games/5916729884/BM-Research-Facility-Sector-C-BETA Motto: "Working to make a better tomorrow, for all mankind."

2 measurements spanning 28 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 313–314 and does not start at zero.
