Codename: ICEMAN a classic true-to-form Sierra adventure, is available now DRM-free on GOG.com.
If you’re not quite familiar with Sierra’s Police Quest-style adventures, you can expect the following: grounded realism based on actual military procedure, plenty of challenge, delightfully retro text-based commands, and a rewarding experience like none other.
If you are familiar with Sierra-style adventuring you know just what you’re up against – this is your chance to step into the shoes of a Naval Officer on a quest to rescue “the ambassador” and prevent total war. To succeed you’ll have to be persuasive, be creative, and you’ll even have to learn how to pilot a submarine – manual included, thankfully.
