Burn Zombie Burn!

I propose to make this trophy in the following way. In the game, go to "SCOREBOARD", look at the rating of one card from the In Space add-on. This expansion contains 2 maps: Engine Room and MothershipBridge. In the ranking, look at how many points you need for approximately 80th place. Then try to earn enough points to get to that place. Well, then, just send a friend invitation to people who are lower in the ranking than you. Once you recruit 10 people as friends, the trophy will open... If anything, you can also create additional profiles on the console and add to your friend list.
