INERTIλ is a Half-Life 2: Episode 2 mod built off of Mapbase. You play as a member of the resistance, and lead a small squad of fighters. It is a fast-paced FPS primarily resembling Half-Life 1 and 2, but with a larger emphasis on movement, caution, challenging combat, some immersive-sim-like features, and inspiration from other games and series such as F.E.A.R., Quake 1, Halo, S.T.A.L.K.E.R., Deus Ex, Counter-Strike, and more.
Work-in-progress HUD changes. There's a new crosshair to accompany the dynamic spread system, the flashlight icon has been moved to the top-right Half-Life 1 style, and a new HUD element has been added on the top-left. This element contains quick inventory information: the player's current carry weight, and icons indicating whether the player is carrying at least one healing item or armor battery.
