There are currently four different Wrenches: the 红扳手, 绿扳手, 蓝扳手, and the Desktop version-exclusive 黄扳手, each placing its respective color of Wire. All Wrenches use the same ordinary 电线 item as 弹药, but the color of Wrench used will determine the color of wire when placed. The colors all function identically, but can be placed so as to overlap or intersect each other without interfering with each other. 分线盒es can further be used to keep intersecting Wire paths of the same color from interfering with each other.
All four wrenches can be combined to make a Multicolored Wrench, a single tool that can place Wire of any color.
Ordinary Wrenches cannot be used to remove placed wires. Instead, a 钢丝钳, or one of its derivatives (Multicolored Wrench , Grand Design ) is required. All Wire colors become the same ordinary Wire item again when freed.
- The Wrench can not be placed on a 武器架.
- Having different color wrenches for each player on 多人模式 can be useful, as each player will get their own wire color.
- Having a wrench or other wire-vision item can be very useful when exploring, as it will make hidden traps much easier to see.
