After being ambushed by monsters on the town's outskirts, he discovers that he can transform into a powerful werewolf.
He continues on to discover who he is, and why he was sent to Foret Town.
When players control as Luke, they are not very strong.
But he is able to transform into a werewolf, which can perform high jumps in addition to becoming incredibly powerful.
Fighting monsters will give Luke DNA data that will allow him to upgrade his beast attacks for more powerful combos.
More beast forms can be discovered, each with their own special powers to overcome previously impassable obstacles.
About Sega Genesis
Known as the Mega Drive outside North America, the Sega Genesis (1988/1989) was Sega's most successful console and Sonic the Hedgehog's original home, fueling the "console wars" era against Nintendo's SNES. Genesis cartridge collecting is well-established: common sports and platformer titles are affordable, while sports-license and later-era games with smaller print runs can carry a meaningful premium.

Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
