- Boarsheads, Lou Guards, and other robots with homing attacks in tight corridors where there's no room to dodge
- Robots that explode into groups of bigger robots
- Robots that explode into huge groups of smaller robots (like a sidearm turning into 10 modula, or a spider turning into 20 green hornets)
- Evil twins and other kamikaze robots that swarm you in tight tunnels
- Hundreds of robots per level, even if the levels aren't all that big
- Crazy puzzles (like you have to shoot a nondescript light on one side of the level to open up a door or wall needed to progress on the other side of the level, and there's no indication which light you're supposed to shoot, and there was one hostage room where the hostage door was indestructible from the front, so you had to destroy it with the phoenix cannon from the back... which I figured out only after scouring the level for a switch to unlock it)
- A guidebot in every level, but the way to the keys is always blocked so the guidebot is always useless and just gets in your way while saying it can't reach the keys
- A boss at the end of every single level
- Nearly every single primary weapon in a single room somewhere in each level, but you only ever really need to use the Gauss cannon since there's plenty of Vulcan ammo
- Lots of earthshaker missiles, but few opportunities to use them (tunnels are too cramped, bosses are often immune to them)
- Locked doors that open automatically when you get close to them, meaning there was no purpose in them being locked in the first place
- "Forcefield doors" that reflect energy weapons and only open if you shoot them with Gauss or missiles
Whoever made this is a jackass, but I secretly kind of love it.
