System Defender/Level 5

:"RED ALERT! The Ultimate Protobot is attacking the EPF mainframe. Battle stations!"
The fifth level of System Defender has the Ultimate Proto-Bot 10000 return after years of absence, and attack the EPF mainframe. It was released on January 14, 2011, along with the release of System Defender itself. Initially, it was unlocked after completing level 1, but was later made available by default. There are 32 slots for cannons. Completing this level for the first time caused the player to earn the Protobot Attack stamp.
==Scenario==
Bots "spawning" refers to when they appear on the map, not when they appear on the scanner at the bottom of the screen, which often happens mid-dialog. Bots also usually spawn in groups, which can overlap with other groups. For information on how much damage cannons deal to enemy bots, see here.
358 total bots appear in this level.
