By default, each clone is a Fighter, the standard free-to-play Bioclass, allowing the clone to have fairly balanced attributes in every statistic. Players who buy a Shadow Depths pass and activate it can unlock the Bioclass of their choice, including Sniper, Berserker, and Miner.

Fighter, Berserker, Sniper, Miner Bioclass

Each Bioclass has a unique skill tree divided into at least four parts. While the Fighter (default and free-to-play Bioclass) only has the four parts, premium Bioclasses have an additional part (five in total) with skills specific to their attributes. This aspect was designed to diversify gameplay possibilities and emphasize the strategic aspect of Shadow Depths. In the upcoming seasons, more F2P and premium Bioclasses will be released, along with new environments featuring unique monsters with distinct attributes. This logic will ensure that particular clones will perform better or worse in specific environments, while opening new strategic gameplay avenues such as cooperation between classes.
