// First Boss
`SectorGuard` is the first real boss wall in Pragmata, but it is also the clearest tutorial for the rest of the campaign. If you understand why the fight wants you to hack first, circle behind the boss, and burst the weak point instead of spraying the front, the rest of the game's major encounters make much more sense.
Weak Point
Back Tank
The orange tank on SectorGuard's back is the most consistent high-confidence target.
Main Threat
Charge
The dash attack is the move most often blamed for first-clear mistakes.
Best Utility
Stasis Net
Repeatedly recommended because it stabilizes hacking windows and rear-angle shots.
Reward
License Key 1
Defeating SectorGuard unlocks the first Shelter progression step.
// Recommended Prep
Both major guides agree that `Decode` is one of the cleanest ways to turn a short opening into real damage. Apply it before your burst, then focus the tank immediately.
For an early boss, SectorGuard moves more than you want. `Stasis Net` reduces chaos, buys safer hacking time, and helps you stay on the correct side of the boss.
This fight rewards short, committed damage bursts more than chip damage from the front. When the rear weak point is exposed, close-range burst is worth the risk.
// Boss Plan
The biggest early mistake is trying to play this like a normal shooter boss. SectorGuard is deliberately built to teach you that direct fire alone is inefficient. Your damage windows are created by Diana, not by just holding the trigger longer.
Launch-week coverage is highly consistent on the two attacks that define the fight:
Once Diana opens the boss, the reliable target is the orange tank on SectorGuard's back. That is the simplest high-confidence rule for the entire fight. If you are shooting the front for most of the battle, you are almost certainly taking longer and exposing yourself to more unnecessary danger.
Coverage from both major guides treats `Critical Shot` as a major burst event rather than a side mechanic. When SectorGuard staggers and the prompt appears, take it. It shortens the fight, simplifies the next phase, and reinforces the game's larger pattern of “hack, expose, burst, capitalize.”
The safest cross-source takeaway is that `Overdrive Protocol` creates one of the best damage windows in the entire encounter. You do not want to waste it while SectorGuard is poorly positioned or while you are still in front of the boss.
// After The Fight
The most stable reward claim across sources is that defeating `SectorGuard` gives you the first Shelter License Key. That pushes your hub forward and unlocks the next layer of Shelter functionality.
Public guide coverage also ties this victory to new Shelter features such as Cabin Coins / Cabin Stamp Club access, additional Unit Printer options, and further Firmware Updater progression.
After the fight, the best internal next step is the Solar Power Plant walkthrough if you are still cleaning up Sector 1, or the full Bosses guide if you want to plan the campaign ahead.

// FAQ
SectorGuard is the mandatory main story boss at the end of the Solar Power Plant sector.
The safest confirmed answer is the orange tank or fuel tank on SectorGuard's back. That is the target most guides identify as the boss's main burst-damage weak point.
Current early-game guide coverage most often recommends Stasis Net for control, Decode for stronger burst windows, and Shockwave Gun for close-range damage once the back weak point is exposed.
The high-confidence reward is the first Shelter License Key, which advances Shelter progression and opens new hub functionality.
