- Demonic Spiders: The grenade zombies. They take a lot to bring down (about as much as a Securitas zombie), and wear helmets, allwing them to No-Sell headshots. Add their impeccable throwing aim with One-Hit Kill grenades that are nearly invisible against the game's dark environments and you have a recipe for gamer rage.
- Narm: The voice acting is... colorful, particularly in the second game.
- Jane Frey is in dire need of acting lessons, and Dr. Bielik's heavy Russian accent will have player's thankful for the existent of subtitles.
- So Bad, It's Good: Despite being an obvious Mockbuster and (or because of) hilariously bad voice acting, the game can be fun at times and the gore is pretty good. It doesn't help that the games are available either as an ad-supported free to play game on the mobile or the paid-for Steam version which is not only cheap, but removes the ads and microtransactions (also rebalance the game).
