Okay, so maybe cruising through Abadox while completely invincible is a bit on the easy side. Maybe you want a little bit more of a challenge... but not a whole lot. Okay, we can do that.

First, go to the "PRESS START" screen

Then grab Controller 1 and press Up, Down, Right, Right, Up, Left, Right, Down, Left, Up

Then start your game. Everything will look pretty much normal... until you pause the game and then unpause again.

If you did the code right, when the action starts again, you'll be loaded to the teeth!

And you can do this as many times as you want, which is especially helpful if you accidentally pick up a gun that you don't want.

But you're still very destructible, which adds just enough challenge to keep the game interesting for a while.

I admit, I never was very good at Abadox. Mostly because I had a hard time finding it at my local rental stores, and that means that I never got what you might call 'passably decent' at the thing. And that means that I saw this a lot the few times that I did play it.

So now when I get the urge to play this game, I go to the title screen

And press

On controller one. If I've done it right, I'll be totally invulnerable!

And since the game scrolls on its own, I can totally start a stage, go make a sandwich, come back and defeat the boss, and repeat until I've sailed through to the end.

Which is totally cheating, yeah, but it's been out for over 20 years at this point. I think I can justify it now.
