Update 15: Stealth Suppressed

We're back with two more co-op & singleplayer maps, as well as brand new stealth options. So suit up, and get ready to experience a more silent and tactical approach to combat.

The stealth options we've included in this update are two-fold. First is the AI's ability to detect different light levels - which means you can now carefully move through the shadows - and second is the addition of an optional sound-suppressor for both the SMG and Assault Rifle. These additions add a whole new tactical layer of decision making to how you approach and complete co-op challenges and multiplayer games.

We've also added the challenging Elimination game mode to the urban combat range of Mainline, and the multi-purpose training arena Colony is now a Survival map, making both those maps singleplayer and co-op.

We've had awesome feedback from the community on the maps we've already released. With the new Mainline and Colony co-op and singleplayer maps, we now have five Challenge maps plus The NeuroGen Incident, with even more to come! We hope Mainline and Colony will receive as much love from you as the other maps have, and we look forward to hearing your feedback on them.

SITREP 8 is out!

SITREPs are all about sharing what goes on behind the scenes as we release each update on our journey towards building Interstellar Marines.

The latest SITREP covers the creation of update 15, including Lukas' work on the two new maps, Mainline and Colony, and Ronnie's new animations for the SMG and AR sound-suppressors.

We also lift the veil on the marketing efforts we have been focusing on to get word out about Interstellar Marines. It's no coincidence the "buzz" around Interstellar Marines has increased hugely since Thordis came on board.

If you have any feedback on the SITREPs, or anything more you'd like to see in them, please do let us know!

Round Up

Update 15 is our third update in two months. We are aiming to release content updates so you and your friends can enjoy new co-op and singleplayer challenges on a regular basis.

Update 15 is also the second update in a row where we've been able to utilise the toolbox we developed whilst creating The NeuroGen Incident. We'll be releasing another update in December which will include new maps as well as new tech, and hopefully an early version of our stats system. This will become the first building block of AI SARA, and will allow us to introduce many new and exciting features as we move into 2015.

In the last newsletter we encouraged you to take part in our video competition with a €50 first prize. Many of you decided to take the challenge and we received many, many great videos. We have chosen three kick-ass videos and asked the community to vote on which one should win the prize. Please cast your vote on which one you think should win - but be quick, the voting ends Friday, November 21st!
