Keep 5 man on top. Like the sniper spot with oracles. 1 brave guardian goes down and take the relic. Stay left in the back where the oracle spawns around the corner. Communicatie with your team. As the relic holder kill many suplicants but don't get cocky, they are lethal. It's best if those 5 snipers on top got the Ice breaker. Never ending ammo is a blessing
