There's a big warehouse filled with loot in Scrap Mechanic Survival but first, you'll need to find the warehouse key.
To get into the loot warehouse, you'll need to find the warehouse key. There are various warehouses around the map and you'll need at least one key to open the doors.
Thankfully, there's a reliable way to farm keys for the warehouse by killing the big red Farmbots. If you kill one and a key doesn't drop, just keep destroying them until you get one.
Scrap Mechanic Survival: Where to find the warehouse key
Red Farmbots can be found near the warehouses and in the reddish, autumnal looking forests. There's also a chance one might appear on your farm at night, which makes the fight more terrifying than usual.
The best weapons to use against them are the likes of the Spud Gun, but you'll need to hit it a few dozen times before it's destroyed, so make sure to bring a 100 spuds or so with you. If you want to use your hammer, you're looking at really long fight and it's a lot riskier being up close and personal with these behemoths.
Try and get yourself up on a ledge away from the Farmbot if you can and keep firing until he's down, then you can pick up the warehouse key. Once inside, you can find some loot but you can't place anything on the ground. Instead, place your lift and drop an item - like an explodable one - on it to use it.
Ecrypters have been found by blasting through walls and vents in the warehouses, but they don't seem to be active yet, so check back soon for more info. The only downside to the warehouse is that many players are experiencing a bug where they can't pick anything up, which is annoying, and you might need to go and kill another red Farmbot to get back in.
