also some more tips :
- use some item highlighter for junk
- remove walls or make them transparent so you can see junk through walls
- recommend using duallog for gathering junk, during waiting for AP to regen you can alttab and gather on other window effectively doubling amount of junk you gather
- use chars with high carry weight (10st, packrat, strongback), max fov (10pe), high ap (10ag, optionally actionboys or +ap items)
