Counterfett's tips for surviving Gold:
- LEVEL: Be level 20. I did it with an 18, but see Egg quote above.
- Infiltrator. I used an Engineer, but the whole rest of my team was Infiltrators. It seemed to make life easier for them.
- Equipment. I only use Equipment on Bronze or Silver Difficulty when I'm playing a new character (live level 1-5), so I had a goodly stockpile of ammo, armor, and weapon powerups.
- Keep your powder dry. Likewise, having plenty of missiles, medpacks, and ammopacks. Don't use them in the early rounds unless you really need to. No matter how bad it seems when you run up against an Atlas and Phantom in round three, keep in mind that it will seem worse when you have a run in with five or six of each on round nine.
