Some PSA's

Turn on enemy team colors. It allows you to see which enemies belong to which team and it even works with sonar and recon.

If you can't see your friends list, you need to re-enable crossplay.

You can prime a canister by meleeing it before throwing it or by throwing it, grabbing it mid-air, and then throwing it again.

The distance you can mantle is determined by the size of your class. Medium and heavy can both jump up to the floor above if the ceiling has a hole in it.

When attempting to mantle, hold the jump button down even if it looks like you missed the ledge. It can be very generous with the timing, so don't change your pathing right away.

Cashouts can be knocked off of the moving platforms using explosives.

Turrets can be placed on top of grabbable objects like plants and then be carried around. It's not super strong though.

Respawn tokens carry over between rounds of a tournament. Don't ever use one if your win for the round is already guaranteed.

Each kill is worth $200 ($400 in deathmatch event). Activating a vault gives $1000 and depositing into the cashout gives $2000 in tournaments. Sometimes it's worth it just to activate a vault even if you have no intention of depositing it.

Cashouts always finish. The timer is increased by up to a minute, meaning that a last-second deposit takes half the time as a regular time cashout.

Got any others?

Edit: Thought of some more:

Jump before the end of non-vertical ziplines and move your aim side to side (not sure if this part is actually necessary) to get longer jumps and more use out of ziplines.

For jump pads, you can place at an angle to give you a much better mixture of verticality and distance. If no angled surfaces are nearby, you can use goo to create one.
