Controls
Select investigation tools, camera views and dialogue choices through the on-screen interface. Examine the information gathered and choose a response before the negotiation timer expires. Recheck new reports when the scene changes.
Simple DS Series Vol. 25 - The Koushounin — About this game
Simple DS Series Vol. 25 - The Koushounin casts you as a police negotiator trying to secure hostages and bring suspects into custody or persuade them to surrender. Seven main cases and a bonus scenario include sieges, robbery and kidnapping. Information from remote cameras, special investigations and colleagues helps build a profile before you choose your approach. Negotiations have a time limit, so changing circumstances require calm decisions rather than simply searching for a contradiction in testimony.
