DLC #1 - Bioshock Challenge Rooms

A Bioshock Royal Rumble!

So, first taste of trophy-related DLC ever. Exciting stuff!
                                      
The Bioshock Challenge Rooms add 12 new trophies based around a series of chambers, requiring a combination of combat and puzzling to complete.

The overall list is very linear, and just requires you to beat the selection of chambers multiple times under various constraints. 

There are also a handful of collectible based trophies awarded for finding the hidden roses in each of the chambers, and although most of them are actually well hidden, there are only a couple to find in each level, so there's no long winded hunt or anything that will add chunks of time onto the overall completion time of the package.

However, there is still a solid challenge to be had from this list;
                                                                                                        

"Worlds of Hurt" - Expert - Rescued the Little Sister in "Worlds of Hurt" in under 15:00, on Medium or higher difficulty

The "Worlds of Hurt - Expert" trophy level is a combination of chambers, rather than just 1 like the rest of them, that you have to fight your way through, and the 15 minute time limit means you have to be fast and efficient, given the fact 15 minutes will require a near perfect run. It will definitely need at least a few attempts, just to get into a familiar rhythm of how to beat the whole run as quickly as possibly, and it might be useful to look up other strategies and follow those for faster success, and to avoid errors in judgement that could cost you valuable time.

It is a trophy that will require skill, and even if you're tactically fine in regards to knowing shortcuts and tricks on how to save time, you will still need to dispatch large groups of enemies with efficiency and skill in combat in order to maintain a good time throughout the whole run. It isn't a trophy you can just pick up and blast through, and co-ordination and practice is a must, but it is a rewarding trophy to achieve.

Most of the longevity in this pack for trophy hunters will probably come from this trophy alone. The first 2 courses an their trophies aren't especially difficult, and nor are the collectibles, but to run the final course in less than 15 minutes requires some precise and near flawless gameplay, and that trophy alone will most likely take longer than the rest of the entire list combined, whilst also presenting a solid challenge at the same time.
