After playing scavenger mod in ITR for like 10 hours or so I can say I do not like it. It's very difficult to get off the ground and if anything happens during the initial lift off period you're basically stuck and have to reset. 
doesn't help that I was playing the beta and the save file got destroyed 3 times due to beta updates, but my most recent try I got killed by unavoidable damage inside an anomaly field. For some reason they added damage that can't be avoided inside gas anomalies and the gas mask actually does nothing against it. And so, all my guns (because I needed to carry them all at once to use the different types of ammo I was finding) and my only gasmask are now stuck inside this anomaly, irretrievable until I find another gas mask and my entire armament is the starting makarov. It's worse than starting fresh because the guaranteed items are now looted too. 

the loot balance is godawful; I find so many fucking sawnoffs and pistols I don't give a shit about inside orange crates. I'm dying for ammo and it's like; another sawnoff? Sure! Wait I heard you want a 5th glock. Ammo? haha no.
