While playing the game, press ESC to access the in-game menu.
Half-Dome icon
About Iceman (CTRL-A): displays the game version and credits.
Help (F1): provides some basic tips
File: Here you can save (F5), restore (F7), restart game (F9) or quit (CTRL-Q) the game.
Action: These actions are better done in-game through shortcuts, rather than through the menu. They are:
Pause Game (CTRL-P)
Inventory (CTRL-I or TAB)
Repeat (F3 or Spacebar): repeat the previous command
Speed: Here you can increase (+) or decrease (-) animation speed or set it to normal speed (=).
Sound: Here you can change the sound volume (CTRL-V) or enable/disable the sound (F2).
Moving your character
You may move the character on the screen with arrow keys, the numeric keypad, or by clicking the left mouse button. To halt your character's steps with the keypad, press number 5, or press the last used direction key again. Do not hold the direction key.
Interaction
You can generally interact with the game by typing simple commands consisting of as little as a noun and a verb. For instance, eat fruit. The game will understand many common verbs, such as look, get, read, load, pry, climb, push, play, tell, use, ask, give, take and so on. You can repeat a command by pressing [F3] or the space bar. You can also right-click the mouse on the screen to look at something without using the text parser at all.
USS Blackhawk control panel
As 2nd in command on the Blackhawk, you'll be controlling the sub from way point to way point, sometimes encountering enemy vessels and even icebergs. While it may at first be a bit overwhelming, you'll find that you won't need to use or observe as many controls and indicators as are present. Note that you can either use the keyboard shortcuts or control with the mouse, whichever you find the most convenient.
1. Map display: not used
2. Fire control panel: Hide or conceal this panel, using the fire control panel activate button (#23). It consists of four controls which are, left to right: select weapon (SHIFT F5) to cycle between Harpoon, Stingray or Decoy, Lock on target (Shift F6), to be used each time before launching a harpoon or stingray, 3-D Imaging display (Shift F7), to be used when dodging icebergs, and Fire (Shift F8) to launch the selected weapon.
3. Vertical sonar: Measures the distance above and below the sub to a solid object like an iceberg or the ocean floor. Not used - just follow the walkthrough instructions and keep an eye on the depth gauge (#5).
4. Ranging sonar: indicates obstacles within 1000 yards radius around the sub. Not used.
5. Depth gauge: displays current depth. You'll watch this one extensively while using the dive lever (#12).
6. Water temperature: Not used.
7. Time clock: Not used
8. Speed: in knots. Used once to keep track of another ship. Otherwise keep an eye on the throttle speed indicator (#32) when using the engine lever (#13).
9. RPM indicator: not used.
10. Stern plane indicator: indicates the angle of inclination of the stern plane. Not used.
11. Coordinate display screen (position indicator): displays the course coordinates of your last way point. Not used.
12. Dive lever Up arrow to dive and down arrow to surface. Used a lot. Keep a sharp eye on the depth gauge (#5) while using this lever.
13. Engine lever: used to adjust the running speed of the sub, using the + key to accelerate and - key to decelerate. Watch the Throttle speed indicator (#32) and if necessary also the speed indicator (#8) when using this lever.
14. Ballast indicator: indicates ballast level in four separate tanks aboard the sub. Not used.
15. Silent running on/off (Shift F4): Activates or deactivates Silent Run. Activate when combating hostile ships to prevent detection.
16. Silent run indicator: Indicates whether silent running is active.
17. Sonar on/off (Shift F3): Activates or deactivates the active sonar. Actually used only once to alert an allied ship of your presence. Otherwise leave it off.
18. Attitude meter: Gauges the vertical angle of the sub. Not used. Keep an eye on the dive lever and depth gauge instead.
19. Wheel: Use left and right arrows. Obviously used a lot. Note that you'll achieve faster turns at high speed. Closely watch the heading indicator (#30) while steering.
20. Closed circuit monitor on/off (Shift F1): displays the actual view outside the sub. Vital to survive your ride between the icebergs.
21. Torpedo tube flood control indicator: indicates whether torpedo tubes have been flooded. Not used as tube flooding works automatically.
22. Torpedo tube flood on/off: floods torpedo tubes. Switches automatically when weapon locks on, so you don't use it yourself.
23. Fire control panel activate button (Shift F2): Lowers or conceals the fire control panel. Used before and after combat.
24. Rudder indicator: indicates the current position of the rudder. Not used.
25. Emergency ballast Control To emerge fast during an emergency. Not used.
26. Hatch indicators: if one of the three hatches is opened, an indicator is lighted. Make sure to close hatch before diving by ordering it through the intercom.
27. Analog compass: Not used. Look at the heading indicator instead.
28. Coordinate display screen (latitude indicator): displays your current latitude coordinates. Not used.
29. Bow plane indicator: Indicates the angle of inclination of the bow plane. Not used.
30. Heading indicator: Displays compass heading in numbers. You'll watch this one extensively while using the wheel.
31. Multipurpose view screen: You'll see the selected weapon, incoming and outgoing torpedoes, enemy vessels, and closed circuit television all on this monitor.
32. Throttle speed indicator: this indicator changes when adjusting the engine lever. There are 6 positions: Reverse (lights red, not used), stop (lights out), slow (1 light), 1/3 (2 lights), 2/3 (3 lights), full (4 lights).
33. Dive plane indicators: indicates dive plane position. Not used.
