Play thirty minutes with every class then lose on maps of the tier which you have unlocked. At first, you will only have the four maps in Tier 1 available. You can view unlocked maps in the private game creation menu. It will indicated how many rounds you must complete in each tier to unlock next one. Playing on locked maps will not qualify.
Start a private solo match on the "Bio Lab" map. After the first wave starts, jump off a cliff. Repeat the process until "Exo Survival Veteran" is earned.
This requires access to the "Riot" map, which is a Tier 4 map that requires all previous tiers to have been unlocked. Play a private game on "Riot". There are only eleven rounds in total. Select the Specialist class, which has Sentry, which will be help until the supply drop. When you get a supply drop with a scorestreak, always take Sentry or Flying Drone. Save your upgrade points and spend them all for Armor after round 9. After a few rounds about four or five rounds, change your Exo to Heavy to get extra damage and health. Use your available Sentries once in each round. Get on top of the main building's entrance. You can reach the roof from either side by jumping on top of the smaller buildings. Snipe enemies from that location. Either use Sentry or wait for them to climb and shoot them as they jump. The last round features an enemy that cannot jump. Get a sub machine gun for round 11. Your Exo will start disabled, but afterwards it will work fine. Switch to the Light class Exo and all moves will be available. After shooting a few enemies you will receive a "Go there" message with a marker. Go directly into the main building and the cinematic will start.
Use this trick to not damage any of the cars. Immediately as you get to the traffic, only worry about getting over to the middle part where all the enemies are located. Then, just shoot down the middle where no cars are. Alternately, instead of shooting them, melee them to be safe.
Mark the target, then take out the two guards near the truck. Quickly go to right over the parking lot and descend as much as possible. If done correctly, you should be able to line up three guards on the lower walkway connected to the parking garage. One of the enemies will walk back and forth. Wait for them to get aligned in a row before taking the shot. If they are taking too long, you will have to follow orders and kill the two guards on overwatch so that you do not fail the mission before returning to this location.
You must unlock the Tier 4 map, "Riot". To do so, you must unlock each tier in succession. Tier 1 is available by default, and you must complete 50 rounds in any combination in those maps to unlock Tier 2. To unlock Tier 3, complete 75 rounds in the Tier 2 maps. To unlock Tier 4, complete 100 rounds in the Tier 3 maps. Tier 4 only has one map; "Riot". Complete round 10 in Riot and a DNA Bomb will drop. It will infect your enemies and turn them into zombies for round 11. Complete round 11 to view a cinematic that shows a large number of zombies overrunning the area.
Note: All Exo-Abilities require battery energy, which cannot be recharged. You can use perks such as Overcharge or Fast Hands to get better battery life and activate Exo-Abilities faster.
Note: Certain Exo actions such as Boost Jump, Dodge, and Dash will briefly make you appear on an enemy's mini-map. To avoid this, use the Blast Suppressor Perk.
