The Professionals II

You control a lone operative moving through a building. Your goal is simple: clear each floor of enemies to proceed to the next. You walk from room to room, and when a door slides open, you have to react quickly. You can crouch for a better shot or run to reposition, but your main focus is aiming and firing before the armed guards inside can target you. Managing your ammo is constant; you need to reload manually between engagements, and letting your clip run empty at the wrong moment usually means a restart. The pacing is deliberate and the difficulty is sharp, with little room for error. It feels like a series of calculated, tense confrontations where a single mistake ends the run.
