Albert Pyun is one of those underappreciated b-movie scifi / cyberpunk / action directors, although to be fair he does have an underground cult following.

My personal favourite is Radioactive Dreams. This is an electric mix of post-apocalypse and a parody of 50’s private eye motifs. It really is a unique experience. Fallout 1/2 were clearly inspired by Radioactive Dreams.

I will agree with @Emperor@feddit.uk, and recommend people avoid anything beyond Nemesis 2, perhaps even just the original Nemesis.

Some other Pyun movies that I would recommend:

• Alien from L.A. (1998) - A nerdy (but very attractive) Kathey Ireland takes part in a adventure lightly based on Jules Verne’s “Journey to the Center of the Earth”.
• Knights (1995) - Includes a mix of many of the motifs typically found in Pyun movies. Post-apocalypse, cyborgs, actions.
