It's Katrina. Thanks for the compliments. I've been writing for years and have several ideas for books too but I've never fully finished one; want to do a couple series and some standalone books eventually. She's one of the main characters in most of them (she's ageless, so she exists in both my fantasy and sci-fi works). One of those books would be the setting that the game takes place in.
Base game would have three episodes of eight levels, starting with simply taking down gangsters who secretly support terrorists, to exploring the ruined sections of an overgrown, ancient city and battling fantasy monsters, to finally taking the fight to a terrorist faction and their demon-loving cult supporters.
There would be three expansions, each with eight more levels. First is desert-themed where you hunt down the remnants of the cult and stop them from accessing the magic of a lost megacity in the sands. The megacity itself is a secret level filled with monsters and several specific threats (mummy curse that slowly depletes overall health, getting enslaved and losing your weapons and powers, trapped in a puzzle box and have to find your way out, etc). Second expansion is more military-themed where you have to stop a separatist front on a forest world; it introduces squad mechanics where you can have teams of weaker allies help you in combat. Third involves you exploring a subterranean dark elf city in search of a magical reservoir of ancient knowledge, capturing its powers before the elves and their allies can.
