Zombies XP Method:

  • Equip the weapon you want to level up and put on energy mine as your field upgrade.
  • Eliminating the Bounty is a quick and easy contract and a fast way to get easy XP.
  • Call in the xville helicopter and kill as many zombies as possible until the helicopter arrives.
  • Rinse and repeat until you reach Max rank.

Multiplayer XP Method:

  • Play objective game modes like domination, kill confirmed, and hardpoint.
  • Use UAV, Counter UAV, and advanced UAV as your kill streaks.
  • Use decoy grenades and play the objective.
  • Use the Trophy System field upgrade to take objectives while you get more kills and XP.

Tips for Weapon Upgrades:

  • Use the weapon you want to level up as your insured slot.
  • Equip Energy Mine as your field upgrade for zombies mode.
  • Use decoy grenades in multiplayer mode.
  • Play objective game modes to get more XP.
  • Use UAV, Counter UAV, and advanced UAV as your kill streaks in multiplayer mode.
  • Use the Trophy System field upgrade to take objectives while you get more kills and XP in multiplayer mode.
  • Look for easy contracts like Eliminate the Bounty for quick XP in zombies mode.
  • Use the villa helicopter to kill as many zombies as possible in zombie mode.
  • Use double weapon XP tokens to level up faster.

Tips:
Advanced drones are unlocked through the new “Arsenal Unlocking” system instead of the level system. This new armory unlocking system can unlock some weapons, KS, equipment, etc.

This is just a preliminary solution used in the game’s early stages. As time goes by, more and better solutions will be discovered by players.
