no clue where to go specially when the maps are huge, bots do not pick up better weapons . i payed like one hour and was not able to find way, was moving in a circle no health kit at the startup . i have played all original campaign and many add on maps with bots on advanced difficulty and had no problem completing them but this map is totally not for single player
I'll give you a little clue for map 1. The objective of map 1 is only to find 3 keys. 2 of the keys are easy to find. The last one lies somewhere & needs thorough exploration. & the healthkits are somewhere in the hidden location. One medkit is usually at the shop near the first spawn location.
As i said difficulty , low supplies are not problem for me , not knowing where to go and getting stuck in very 1st map for one hour is. may be i should play this map on easy just to remember the path and then replay on advance difficulty. Thanks 4 the advice...
Actually it's better to try this campaign in normal difficulty first, to memorize the paths & clues. I finished this in singleplayer in normal difficulty. The lack of weapons & supplies are hard for advanced difficulty. & unlike all original campaigns that are linear & all we need is just follow the paths to reach the safehouse, custom campaigns have more variable types, like puzzles, traps, labyrinths, boss fight maps, etc. This campaign traps, puzzles, & labyrinths at once so it's considered as a difficult campaign. It's better to try campaigns with easier puzzles, traps & labyrinths first before taking this campaign. Actually "Powerstation" campaign has much higher difficulty than this, because I couldn't finish that one in normal way, while I could finish this in normal way though it took very long time to find the clues & solve the puzzles.
not for singleplayer, unplayable with bots
