This isn't as difficult as it looks I managed 25 / 100 in one game.
https://imgur.com/a/21Q7Gv2You want to use Maeve as she's the best character for this gamemode 100%
You want to use the following 3 mods:
- Hasten (increase vanish movement speed bonus by 100%)
- Amplified (increase siphon damage by 10%)
- Shifty (increase vanish duration by 2 seconds)
This I found is the best setup recycle other mods as soon as possible to afford these 3.
It gives you the ability to dip out of every fight with ease, but also the weapons necessary to kill someone else on the other team who may be camping with a huge amount of batteries.
The cage and maeves special to teleport to any enemy on the radar means you can be aggressive and defensive when you need to be.
If you do reasonably well and have a half decent team you should finish in 10 games or less no problem. (Providing the gamemode pops up!)
