Instructions

Difficulty: Challenging

1. Beat the Campaign. You’ll earn ten Achievements if you do this on Normal difficulty, another if you do it on Heroic and another if you do it on Legendary.
2. Find all the Skulls in the Campaign mode. There are 9 in all, each in a different mission.
3. Locate and access all the terminals in the Campaign mode. Easier said than done, but is worth 40 Gamerscore.
4. Score 15,000+ points on the Meta Game in each mission. The only exceptions are the sixth and seventh missions. In each of those, you must earn over 50,000 points to earn the Achievement. There are nine of these in all.
5. Earn a total of 70 Online Exp and a Skill Level of 10 through multiplayer battles. This will earn you three Achievements and the rank of Spartan Officer.
6. Use the Spartan Laser to destroy a vehicle and to kill two people at once in Multiplayer matches.
7. Experiment in Multiplayer matches. All the remaining Achievements are earned by doing things in Multiplayer battles like sticking grenades to people, killing 5 or 10 people with specific weapons (like the Needler) or scoring 10 headshots on a single map. Be adventurous, use a variety of weapons and get in the game!
