Let me first say I don't cheat and I never would cheat.
I do however know how cheat programmes work and have researched it quite a bit. I'm not going into too much detail about how and what since I dont want to give people any Ideas.
But:
A lot of stuf in this game is done serverside. Because of this you can't do any of the following things you stated:
- Sink ships: The damage is calculated serverside, a hacker can't trigger this type of thing.
- Become immortal: Your computer tells the server where you shoot the other persons computer tells the server where he's moving. The damage is calculated by the server and the server decides if someone is hit/ hurt/killed. Because of this you can't hack immortality into the game. Hitmarkers can be wonky, your client side calculation decides the hit marker and with some lag it might be fooled.
- Kill you in one shot: Again see the above mentionex explanation. It's impossible to fool the server. You could make a hotswap between two guns and make it seem like 1 shot (there's no animation lock on weapon switching)
More likely scenario:
You got in a fight, ran away, had damage (hit shallows for example) that none of you guys heard and sank. (I've seen ships go down with 1 hit to the hull because they were all too busy doing other things). You tried to defend but were outclassed by the other crew, maybe you had some lag and got hitmarkers while missing maybe they ate bananas a lot.
Don't post cheating incidents on the forums it's just not the place for it. The chances of actually encountering a cheater in a game like this is verry slim. The game isn't popular enough and because of the serverside calculations the options are limited.
Make a report, provide evidence with it, if it's a cheater he/ she will get what's coming if not you might just not be as good as you expected.
Losing is a part of the game as much as winning is.
