What are the upgrade contracts in killer 2?

Upgrading the contract is a game, and the task of completing the contract can be upgraded as required.

Officials say there will be six locations when the game is released, and each location will have multiple tasks. Every map in killer 2 is a large-scale interactive sandbox, and there is something worth exploring everywhere except the simple assassination process. Old players can directly explore every corner of the map, and in order to let beginners know what the game really wants to provide, the game will play a mission briefing before starting the level, telling players who the goal of this level is, why they choose to kill this goal and the consequences.
