Radical Entertainment has said it's working hard to ensure Prototype gets a release in Australia and Germany - even if that means cutting the level of violence in the game.
Both regions are notorious for demanding cuts, but Radical's marketing director Chris Ansell has said the team will face the challenges and work closely with ratings authorities to ensure release.
"We're working really closely with the German office and we've had multiple meetings with the USK," said Ansell.
"They've seen it a number of times and we're making very detailed analysis of the particular elements we need to change and tweak and we're always watching the other titles and what they have to change. It's a large job for us to do, I won't lie. It's a challenge that we've said we would tackle and take on."
Radical has toned down ragdoll physics on dead bodies, levels of blood and dismemberment, and has said the producer currently has a "very long list" of changes and tweaks.
Despite the extra work, Radical hopes to ship the edited title in Germany and Australia at the same time as the other versions of the game worldwide.
"We've not confirmed simultaneous shipping with low violence but that's the intention for us," revealed Ansell.
Asked whether having to make changes to a game that was conceived for a mature audience was frustrating Ansell admitted, "It's not ideal."
He continued: "We set out to make this game a mature-rated game like any mature movie, people who buy this will be over 18. That's the area we're playing with.
"But obviously it's a challenge that we all face and we have to respect this and make the best possible game we can within those restrictions. But yes, in a perfect world we'd have complete freedom. Maybe one day things might change.".
Prototype is out on PS3, Xbox 360 and PC this summer - visit Eurogamer later this week for a full preview.
