To help make the Wreck Age Seed Bank starter pack an even better value, it includes a bit of terrain. This generator is the big piece, though it also comes with a variety of small bits that seem destined for the bit box.
The terrain itself seems to be from the Mantic Industrial collection and fits right into the setting. Painting terrain, and especially industrial / post-apoc terrain, is a fun excuse to be sloppy. Here I’ve used a grungy mix of oil washes, sponge chipping, drybrushing, and AK weathering pencils. The messier the better.
