Case Study #312 — Software Failure Events Timeline

Helldivers 2 launch server-capacity crisis

Arrowhead Game Studios' online co-op shooter Helldivers 2 became a surprise global hit within days of launch, but its servers were so overwhelmed that the ~100-person studio had to publicly advise people not to buy the game until it fixed severe login queues and dropped connections.

02 — The Root Cause

What the software actually got wrong

The developer's server and matchmaking infrastructure, along with third-party rate limiters on concurrent connections, had been sized for a modest hit rather than one of the best-selling games on the platform, forcing Arrowhead to repeatedly renegotiate capacity with hosting partners and raise its concurrent-player cap several times over three weeks before service stabilized.

How Requs AI Catches This

Requs AI Edge Case flags this exact pattern at the requirements and architecture stage — before a single line of code implementing it exists — so the assumption behind it gets challenged while it is still cheap to fix.

03 — How This Gets Caught Before It Happens

Beyond code coverage and "shall" testing

Root causes like this one rarely show up in code coverage or requirements-compliance testing, because nobody wrote a requirement anticipating the specific edge case that broke. Requs AI Edge Case and Requs AI Software FMEA are built to surface exactly this class of overlooked failure mode — before the software is written.

Requs AI Edge Case

Surfaces this before code exists

Identifies edge cases like this one at requirements and architecture time, using the Common Defect Enumeration to catalog failure patterns seen across hundreds of real-world software failures — including this one.

Requs AI Software FMEA

Connects the failure mode to the hazard

Traces this class of root cause directly to the system-level hazard it can produce, so a defect pattern like this one gets flagged during design review instead of after it ships.

Find the overlooked root causes before they ship.
