Holding E on a player to open up two options: Trade, and Search.
The first option opens a trading window with the other player, where people can safely trade objects without having to drop them down. (I know, it seems so obvious, that I feel it’s already in the game and I just missed it. However perhaps this is intentionally not done? Still, the rest of the suggestion would be beneficial even without the safe trading option.)
The second option allows you to search a player. Both players have to stay still for 2-3 seconds, without weapons out. Any action aside looking around breaks the search. On successful search, the player can see all another person has just like when looting a sleeper, but minus the ability to take items.
On a related but different suggestion: Let us have some way to see if a player is crafting something, either by an icon or some text when you look at them.
Those ideas all go in the idea of giving players more “tools” to be able to do whatever they want, while feeling safe about it. Alternatives, so you can work with others in an easier way.
You want to let someone in, but can’t trust them? Have your buddy search them for weapons. Search him again when he leaves: Maybe he stole something when he was inside!
Or what if he’s already inside, he brought resources to craft a weapon and ammo? He does so and stabs you from behind. Bad.
Could see that work in all kinds of situations. Gambling towns, betting on arenas, trading areas, whatever can be made that requires a degree of “safety” that trust alone doesn’t let you have. “In Rust, never Trust”.
And so you can finally know if that naked is really what he looks like, and you haven’t impacted any other part of the gameplay. A win-win, isn’t it?
Do let me know if this already has been posted, the search function isn’t treating me well today, keeps throwing me to the Cloud error page. And comment ahead!
