Spawn as much chickens during the whole round, don’t ever get stunned in the game, not even once, once you get stunned you will lose the entire round.

Use mist immediately when you have missing health. Try to keep your health at max. Or save the mist when the boss is spinning since there’s enough healing involved

Just press down the weapon aim button throughout the whole round, even when pressing gadgets. No need to avoid the boss even when it’s spinning, just keep aiming 24/7

All the best :))
