Mulighederne for at skræddersy dine egne våben, bliver tilsyneladende et endnu større aspekt af det kommende Dead Space 3, end nogensinde tidligere i serien.
Til AusGamers udtaler associate producer Yara Khoury således at dette aspekt alene, kan tilføje op til hundred timers ekstra spilletid, hvis man altså ønsker at udforske alle aspekter af systemet:
"If you are into weapon crafting, you can spend literally one hundred hours in this thing. If you want to explore all the beta-paths; if you want to replay with the co-op; it's way more about choice in Dead Space 3: you can really spend a lot of time doing that."
