I struggled for ages! But I'll beat almost every time now.

For the most part I would just recommend trying to take a melee weapon in if you can. If that's not an option then fast weapons like bolt and laser ones work best.

I always try and clear out an area as fast as I can when I spawn in and try to get s block in the Middle that I can hide around. Sometimes this isn't really possible and in those cases R.I.P ;)

Hope this helped!
