Tips/Strategies

General/Fundamentals

• Keep your distance from the Tank at all times, regardless of what abilities it may have.
• You should only close in when the Tank is distracted or stunned.
• Check if the Tank is immune to bullets, fire, explosives, melee hits, and/or bile bombs, and adapt accordingly.
• Take off-angles and chip away at the Tank from different directions. Rotate to different positions when you are being targeted.
• Take initiative by distracting the Tank when you see it focusing one of your teammates.
• Maintain uptime by constantly dealing damage and looking for ways to help your team.
• Be aware of your surroundings and don't fight the Tank indoors or near environmental obstacles, such as water.
• Making a run for the saferoom is not advised unless you are the only one left standing and the Tank still has a lot of health. It's better to finish off the Tank as a team.

Solo

• Use your bot teammates as distractions for the Tank.
• You will mainly have to rely on guns and throwables to deal reliable damage from medium to long range, since hitting the Tank with melee weapons or getting hit by the Tank will create acid puddles under your feet.

Multiplayer

• You and your teammates will have to take turns distracting the Tank.
• Be smart with your ammunition and throwables by coordinating with your team.
• If you can stun the Tank, open fire on it as a team to finish it off quickly.
• Look for openings to revive any incapacitated teammates or heal any limping teammates to maintain a numbers advantage.
• You may have to risk taking hits for your teammates to make sure they don't go down.
• Communicate to your team the location of any nearby acid puddles.

Combining with other abilities

• When this ability is combined with other abilities, it can be a lot harder to kill the Tank. Apply the fundamentals listed above and bait out other abilities to get them out of the way (unless they are one-shot abilities).
• The Tank can only be as oppressive as you allow it to be. As long as you play smart, either solo or with a team, it won't matter what abilities the Tank has.
• There are some abilities, such as Ice and Slow, that can make this ability deadly, but as long as you keep your distance from the Tank, they shouldn't be a problem.
