May I use the default FPS asset from Unity in a Commercial game?

The title says it all

The FAQ makes it sound like you can use their assets, but they don’t recommend it.

But how would the player now I used it if it’s a fps premade?

They probably won’t, but I still wouldn’t use it for a commercial game. Write your own or use - for example - UltimateFPS, if you have the budget.

Okay thanks for the answers!
