If you know which ones you are missing, you can easily create a match with the needed map on Bronze difficulty. It will quickly fill up with randoms, and off you go! Finally, extraction is necessary for the map to count. However, on Bronze difficulty this will be easy.
There are a total of 6 multiplayer maps, and 6 N7 missions.
SP: The N7 missions are not story related and are optional quests found within the campaign. You must actually do them all before you finish the game or you will have to resort to multiplayer in order to gain the achievement.
MP: You just have to finish all of the waves for each map. This can be done on the Bronze difficulty to make things easier. Best done with a full team and with a few levels under your belt to have upgraded weapons and powers.
Single player: There are six N7 missions to complete. They are given to you by the Alliance through emails or by Specialist Traynor. The missions are list below. You must complete them all before attacking Cerberus Headquarters.
- N7: Cerberus Lab
- N7: Cerberus Attack
- N7: Cerberus Abductions
- N7: Cerberus Fighter Base
- N7: Fuel Reactors
- N7: Communication Hub
Multiplayer: There are six multiplayer maps to complete and it is basically a survival mode. All maps, difficulties, and enemy types are all available from the start. Communication and team work is the key to completing all 11 waves on each map. The maps are similar to the maps encountered during the N7 missions and other side missions from the main story. Bronze difficulty is the easiest to complete all 11 waves.
Most of the 11 waves are the standard different combinations of reapers, Cerberus, or geth enemies (one type per match). Waves 3, 6, 10, and 11 are special. Waves 3, 6, or 10 will be one of three things, kill four specific enemies within the time limit (about 1 minute per enemy), hack one computer within 5 minutes (this goes quicker with all four people in range of the computer), and deactivate four devices scattered around the map within 5 minutes. Wave 11 is different since that is the extraction wave. You and all of your teammates must get to and be inside the extraction area within two minutes. You can venture outside of it, but all four of you must be in the zone when time expires for the full bonus. While you're waiting, enemies of one of the three types (including the several of the strongest) will infinitely spawn and move to the extraction point.
The six maps are listed below.
