Currently you can only use c4 or pickaxes to raid. I have a few ideas to have more variety.
Code Lock Hacker- If electricity/wiring ever gets implemented in Rust, maybe a hacking tool could be made with a wiring kit and it basically has a 1/10 chance to successfully hack the door and gets destroyed on use.
Drill- A placeable drill that could shred through armored doors. Would require a lot to make and it would take about 1 minute and 30 seconds to get through an armored door, and less time with weaker doors. It would have a chance to instantly break, an if it doesn’t break, it could be used again, but with less efficiency.
