SteamWorld Dig

Rusty can explore the mine by hacking away dirt with the pick-axe.

The goal is to find treasure and additional equipment which is required to be able to proceed in other areas, e.g. a drill allows to break stone.

However, those gadgets require water which can be refilled at water reserves which can be found in the mine.

Other obstacles are traps, enemies, switch puzzles and platforming sequences.

It is also advised to watch for rocks - when Rusty removes dirt under them, gravity comes into play.

The found precious metals or gems have to be sold on the surface - fortunately there are teleporter and elevators which shorten the way - for money which in turn is used to buy upgrades (e.g. more health points or a bigger capacity for carrying treasure) or equipment (e.g. dynamite for killing enemies, ladders or lanterns).

Some upgrades additionally cost energy balls which can be found inside the mine.

After dying, the people on the surface repair Rusty against a fee.

SteamWorld Dig for PlayStation 4 is currently worth €21.12 loose, €52.80 complete in box, and €126.72 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

SteamWorld Dig has only a handful of tracked market sales, suggesting relative scarcity compared to more common PlayStation 4 titles.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For SteamWorld Dig, loose is €21.12 and CIB is €52.80 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of SteamWorld Dig is currently worth €21.12 loose, versus €17.44 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
