Aside from the now-released Surviving Mars Da Vinci update, which focuses on providing a lesser challenge if you want it to, Surviving Mars is also slated to receive an update that does the opposite - provide a greater challenge than the base game does.
Titled 'Sagan', this update is currently planned to release in September, and will offer 24 entirely new major challenge for the players to try and overcome over various playthroughs, as well as a UI to rate the manner in which you do so.
Surviving Mars is a bit of an innovative take on the old genre of city-builder games, and brings with it a number of tweaks and changes that are necessary for this sort of gameplay to work. That said, the game did need a number of alterations before reaching its potential, and Da Vinci Update brings it closer to that.
Included here is Creative Mode, where players will be able to tweak their desired difficulty. Here lies such stuff as the ability to disable building maintenance, easier researching, a general gameplay speedup, increased funding and more! However, making great use of these resources also disables achievements.
The rest of the newly introduced stuff is no less important, mind. Players will now be able to set a desired amount of resources in any given depot/storage unit, so that resource collectors make an attempt at keeping you topped up automatically. The rework of storage UI ought to help as well.
There's also the energy network rework, where players will no longer have to set up individual cables between units. A new 'follow' camera has also been added for individual vehicles and colonists, if you're curious as to how they're spending company time.
This all comes with a rather long list of rebalancing, fixing, UI changes, modding additions, and disaster alterations, which you can read in full on the official website. If you were excited about the concept of Surviving Mars but didn't want to give the game a chance before, now just might be the right time to do so!
