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."

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
