Keith Elwin deep-dive on Avengers design, modes, and Stern's code quality improvements.
Iron Maiden will receive a major code update in 2020 with tweaks and changes, likely the last significant update barring glaring bugs
high confidence · Keith Elwin states this directly when discussing Iron Maiden end-of-life cycle
Ray Tanzer was hired to help with code implementation and rules debugging, providing feedback on playtesting
high confidence · Keith discusses working with Raymond on Avengers and Iron Maiden rules, mentions Raymond got a playfield to test
The Captain Marvel ramp in Avengers: Infinity Quest (Premium/LE)/LE is the most expensive component, too costly for Pro model, leading to substitute stand-up target with spinner and spring gate on Pro version
high confidence · Keith explains the design iteration and cost-driven decision in detail
Avengers shipped at version 0.91 or 0.92, representing improved release quality compared to older Stern games
high confidence · Host notes Avengers shipped at 0.91/0.92; Keith confirms Stern has improved code quality over time
Keith designs with two player types in mind: score-focused players and story-focused players, with accessible story progression but deep scoring potential
high confidence · Keith explicitly states this design philosophy when discussing Power Gem mode design
The Gamma Ray shot sound effect in Avengers was originally created for Jurassic Park but unused, then repurposed for Hulk Rage mode
high confidence · Keith details the sound design process with Jerry Thompson and Rick finding the archived sound
Time Gem is the hardest mode in Avengers by design, as winning it extends ball savers and super mode duration, making it high-risk/high-reward
high confidence · Keith explains Time Gem's game-changing effect and intentional difficulty balance
Soul Gem flipper count mode was tested in Jurassic Park as a bonus mode before being made a main mode in Avengers
high confidence · Keith discusses using Jurassic Park as an experimental testing ground for the flipper count mechanic
“I know there are two different types of pinball players. Those who play for score and those who play for story.”
Keith Elwin @ ~27:00 — Core design philosophy explaining how Avengers accommodates both casual and competitive players
“It's tough being one of the go-to designers, right? I mean, I love being busy. I love working. So I'm not complaining.”
Keith Elwin @ ~12:30 — Reveals production pressure at Stern and Keith's workload managing multiple simultaneous game designs
“We have critical blows and glancing blows. The critical shot is worth three times as much as the other two.”

“Yeah, this is super boring... I went back to the drawing board and I was looking through what assets we had for Dr. Banner which were basically his eyes.”
Keith Elwin @ ~31:00 — Details creative problem-solving under design constraints for Gamma Ray sound and animation
“Yeah, barring any glaring bugs, this will be the last update. It doesn't make sense for us to spend a bunch of time on a game that's three years old.”
Keith Elwin @ ~14:00 — Confirms Iron Maiden reaching end-of-life and last code update coming in 2020
“I put a spinner there and a spring gate. The only purpose of a spring gate is to slow the ball down because the ball is never going to come back through the other way.”
Keith Elwin @ ~21:00 — Technical explanation of Pro model Captain Marvel ramp substitute design solution
“We've definitely gotten better... The fact that I'm doing all the rules and scoring changes, I do know that in my head, Rick just has to go in, figure out how to implement it.”
Keith Elwin @ ~18:00 — Explains workflow optimization with Rick Nagel that improved code quality and release speed
“If you shoot the affected avenger before shooting the disc you get to skip that final blow to the sanctum which can be a bear.”

high · Keith explains gem mode difficulty hierarchy and intentional design: 'great power comes create difficulty' and balances modes between too easy/too hard
personnel_signal: Raymond Nagel recently hired at Stern, given Iron Maiden code project as learning opportunity; now collaborating with Keith on rules debugging and Avengers

code_update: Stern's code release quality has significantly improved; modern games ship at 0.91-0.92 vs old standard of 0.41, suggesting better pre-release testing and implementation
high · Host praises improvement from old practice of shipping at 0.41; Keith confirms 'we've definitely gotten better' with improved workflow
