: If you are downloading the "full version," make sure you're getting it from an official source like Steam or the developer's website to avoid malware that often hitches a ride on "free full version" links!

: If you use heavy explosives to clear a path in Mission 2, those buildings remain destroyed if you have to retreat through that same area in Mission 5. This forces you to think about the long-term layout of the "blockade" rather than just the immediate firefight. How this improves the game

: As your character faces more intense combat or exhaustion, the UI and environment subtly distort. Objectives might become vague, or enemy positions might be "hallucinated" on the map, forcing you to rely on sound and visual cues rather than just icons.
