Alan faces familiar obstacles in The Signal including violently possessed objects and people. However, these threats are condensed into smaller, more interesting areas. The strange new environments have more interactive elements that add to a brand of combat that some people felt was too repetitive in Season One. Enemies are clustered more tightly together, there are more explosive elements, and Alan's written words have tumbled out into the world to act as item drops and puzzle triggers. In one section Alan's flashlight -- which has always acted as a shield from harm -- becomes a trigger to release more threats if the beam of light touches certain objects. In another, the flashlight can ignite explosions by passing over specially marked objects... it's amazing to me that these clever mechanics weren't in the original game.
