With "quitting" I mean every form of ending the mission for the invader without him killing you (like dying to an npc or kicking him).

Beginner: Quit instantly upon invasion. Perfect for ruining a hunter's anticipation.

Intermediate: Stick around for 10 minutes or until you are tagged before abruptly quitting.

Professional: Wait it through - until you’re killed - then leave instantly. The Invader will not get the win nor the kill. Make your opponent feel like they just wasted all that time for nothing.

Perpetual Crawling: Never stand or crouch if you can help it. Move like a sluggish worm around the map. When detected, change positions in a completely illogical manner to frustrate the invader. Your point is not to do objectives here, but just not to get spotted or killed at any cost.

Camp like a Champ: Pick an almost unreachable spot, cover it with mines, and sit back. If the invader tries to reach you, they’ll need a defusal team. (Just watch out to not get kicked for camping)

What is a Side Mission?: Only do what’s absolutely necessary to complete the map. As soon as the final objective is ticked, head to extraction immediately. Don’t linger - leave the invader cursing at the screen as you escape - probably minutes after he connected.

Friendship is Love: Allow other players to join and leave at will. Best if they keep popping in and out, flooding the invader’s screen with “Player has joined” and “Player has left” notifications. Confusion is your best friend here.

It's a Trap: Place traps everywhere! Every doorway, every corner, every body, even in completely useless locations. At best, set them up before engaging any objectives. It’s not necessarily about killing the invader - it’s about making them paranoid.

Be the ultimate Enemy: Don’t turn on invasions until you’ve mastered every map solo on authentic in a ridiculously short time frame. Then, play any preffered map, switch to very easy, remove the lung assist, and wait for your invader. Make them feel like they’re chasing an untouchable ghost, only for them to get shot from across the map when they least expect it.
