How do I get into Bio's Trio Zone War Mode?
On the game modes homepage, you will see, at the bottom, the “Zone Wars” mode, which you have to click on.
Once in the mode, you will have to make your team (whether you are alone or with friends), by entering colored portals, allowing, in particular, to make your arsenal. Note that the weapons are to be distributed between each member of the trio, so it must be done with accuracy and reflection, while not wasting time. The game then starts and the goal is to be the last team alive, eliminating their opponents.

Note that you will have to build to protect yourself from others, in particular, while progressing towards the center of the area. A very energetic mode.
As for the challenges to be validated, here is the list:
- Deal damage to players in Bio's Trio Zone War
- Get kills with headshots in Bio's Trio Zone War
- Regain HP or Apply Shield in Bio Trio Zone War
- Help your teammates score eliminations in Bio's Trio Zonal War
