The signal translator is suuuuper cool looking and very useful in multiplayer, plus there are several mods that hook into it for horror purposes to broadcast enemy messages... but you would never buy it in solo because there's no one inside to hear your message. I propose a mod that causes the ship to monitor the player on radar (in solo, just the player) and automatically send out helpful transmissions. The simplest example would just be "12pm"/"6pm"/"9pm", but also "prox alert" if a red dot shows up onscreen, "turret" if the player nears a turret, etc. That last example would probably have saved me a few times at least in solo. Maybe add a toggle to turn the messages off by interacting the translator.
Other ideas for this translator upgrade include:
Opening doors/disabling onscreen turrets automatically for the targeted player (definitely good for solo players who don't have an ally and can be entirely doomed if they find a turret hell map).
Teleporting spinning players.
Ominous messages already done by other mods, this just gives solo players reason to buy the translator so those messages play.
The basic idea being that the translator is packaged with some kind of radar analysis equipment that detects when the onscreen player needs to know something or needs a code sent out. The terminal doesn't come with this feature standard, hence why the player needs to buy a 255 credit device to unlock the function (and for balance reasons I think).
