*RAIDING* (when I refer to wall or ceiling, it would mean stone or metal)
Raiding a very hard process for a beginner. As described above, and using rustdata, you can determine the best route into finding loot.
If you have a smaller base, such as a 2x2x1, you can easily get on the roof with a friend, and shoot at the middle of 4 panels with 4 rockets. Pic related. The reason for this is because rockets cause splash damage, so if you hit the middle, it distributes evenly across the 4 panels. It doesnt matter if they are walls or ceilings.
C4 does not cause splash damage, therefore is never used unless found in loot crates. Refer to rustdata for c4 usage in raiding.
When getting into a base, you either are going for loot, or you are going to fuck them over.
If you can manage to find the building cabinet, then great! You may be able to build up further to help advance your raid, unless they did the "top-down" method described above.
When raiding and you encounter a sheet metal door, it is always in your best interest to use 1 f1 and 1 rocket (if the door is full health) It saves on gunpowder usage and you may get some dank loot.
If you know for a fact that a 2x2x1 base has only 2 sheet metal doors before you get to their loot, you can just use 2 rockets and 2 grenades to get in rather than using 4 rockets on top the base. You dont always have to go for cabinet, but if you do, just hold RMB and hit clear cabinet, authorize and lock it in, making sure there is no way for others to access it to recover the base.
BEDS: Sleeping bags are the most basic form of respawning (besides randomly respawning) They are great for space and can be placed anywhere on the go, but they have drawbacks if you die multiple times in a row The respawn time can build up quick so its always good to build a bed which always has a 30 second respawn time after your 2nd death in a row. Beds can only be placed on foundations or floors.
