Couple of questions

[Kapitan]

2. Is there any way to switch between platforms during a mission? So If I'm in the ship, and launch the Helo, can I switch to the helo?

This is not possible

3. how can you tell when a wire guided torp has a solid lock on a target? Sometimes, it seems like it should lock to me, but when I engage it, it goes into it's search pattern even though the target is directly between the red lines.

When it has lock you will hear loud pings ever half second to every second go to your active intercept screen look and see if the bars are going green to yellow or yello to red if they going green to yellow or further then its locked you, best move out realy is to drop countermeasures and hard turn 90 degrees but be warned doesnt always work.

5. Where can I find how much fuel/battery is left? Is it possible to run out of fuel?

The frigate will never run out of fuel to be honest unless your sitting at your computer for a month you probably wont run out of fuel infact it doesnt have a fuel setting because the missions are considerd short some of the longest missions you may do will take a few hours and you realy are not going to use a full tank in that time even at flank all the way.

The kilo can run out of battery you will find this on the ship control panel near where it says port and starbord engines its a dial with a percentage meter on it, if your very careful you can definatly get 24 to 36 hours out of your battery but if your reckless you will be surfacing within the hour, only to find that my akula is on your tail.

Good luck Good hunting God speed
