Complete all seven optional tombs to get the 'Intellectually Superior' achievement. Solve the puzzle in each tomb using the indicated solution to get a reward for each tomb completed. Search the indicated locations to find all seven optional tombs. Note: You can quite in-between rounds and will still retain all XP and salvage you have obtained. You can then start a new match, and repeat the process. The salvage respawns pretty quickly after collecting it. On the way to each of the medkits, you can stop and collect salvage. Simply sprint to each waypoint, and collect the medkits as they appear, then return them to the drop-off point. A white waypoint icon will appear off in the distance showing where the medkit is located. Once you appear on the map, there will be a circle near the spawn point where medkits are dropped off. Even though the medkits spawn randomly, there are some locations the medkits will always appear. Then, retrieve the medkits scattered randomly around the map as quickly as possible. Set the 'Medkits To Retrieve' option to '20'. This method usually takes 8-10 minutes to complete. Change the 'Time Limit' to any time desired. Exit the Loadouts screen, and select 'Match Options'. Leave the Survival Skill set to 'Advanced Looting'. Choose the top option, and when you are at a high enough level, select 'Second Wind' as your Offensive Skill. Select the Survivor team, then customize your Loadouts. Select Rescue mode, and choose the Beach map. At the Multiplayer menu, create a private match. It can be done solo or with other players. This trick allows you to earn 10,000 XP and 2,000 salvage or more approximately every 5 minutes.
