It was a long journey from our initial Bronze matches, via a lot of hard Silver matches to the gruesome Gold battles. We had to play on Firebase Dagger with only three players because of server side problems but still somehow made it. It took us three attempts (spread over two weekends) and a strategy change before we finally won on Firebase Reactor. We even managed to complete a retrieval mission during wave 10. After that fight the final Gold match on Firebase Ghost felt almost easy.
When the trophy finally appeared on my screen it felt really good, in particular because we did this as a team.
