We love to be scared, and Slender manages to do just that. Some would say that Slender isn’t so much of a game as it is a short, interactive experience that’s built right into the browser—but we think otherwise. If you love scares, do yourself a favor and play this one with the lights off and the headphones on.
Slender is played through the browser, but that don’t let that stop you from thinking it isn’t anything but a real game.

The game is split across a variety of game types and maps, largely offering close quarters battles in which players engage in classic death match modes, Capture the Flag, or fight for dominance over specific objectives on the map.
Blacklight’s maps are filled with weapon depots, in which players can purchase upgrades with points accumulated during play, for ammo, better weapons, and even hardsuits, small-sized mechs that can be mounted by players to provide an edge on the battlefield. One of the game’s biggest feats is the customization of weapons and armor.
