To Doborog:
There should be a way to detect if the player has more lives or upgrades points than it should have, and, if the game detects that you cheated, it will send a special message:
Commentatron: Analysis-Bot, what can you say about this human?
Analysis-Bot: The human is a hacker! It hacked poor Upgrade Bot to become invincible!
Commentatron: Well, then we have a special challenge for the human...
After that, your occupation will instantly change to "Hacker", and, the next round will be your last one...
After going up the elevator, you'll be greeted by 5 MK6 "Spidertron 6000" Arachnid Bomber Automatons, and 15 MK2 "Jetpack Bots" Rocket-Powered Assault Robots. And, the robots are constantly falling from the sky, so, even if you manage to survive it, you'll be greeted by more Jetpacks to the face, and it also removes all of your clones too!
