Rocksteady is an original font design for pretty specialized applications. It's super bold and irregular, with two different character sets. The upper case just looks like a bold, rough-hewn alphabet, but the lower case looks like the same characters but assembled from stacked, rough stones. Hence the name and the rock themed preview graphics.
Rocksteady could be a fun font for special purposes - book covers, music labels, maybe a construction company logo. It is somewhat inspired by pulp novel cover lettering.
You can try the DEMO version of Rocksteady for free. It has selected characters from each character set. You can ORDER the full version for only $24..
