WELCOME TO HYDRO!Get-to-grips with vintage machinery from yesteryear!  The local township has directed old No. 101 Hydro-electric Power Station be pressed back into duty and you're the sole custodian for the job!Keep your wits: not only generating power quietly, without blowing fuses or starting fires, but also managing and maintaining your power station's supply levels (e.g. gear oil, fuses, battery acid) to keep it running smoothly.You'll also need to manage your fatigue levels and work efficiently to stay profitable and keep your funding levels in the green - or risk shutdown by the township's council.WHEN THE RIVER IS WILD...Generate power day and night so long as the river is flowing fast.  Your main goal in Hydro is to generate electricity for the Township whilst dealing with obstacles that come your way.Work both day and night shifts, encounter unique events and township power demands based on the time of day.CONNECT ("SYNC") TO THE TOWNSHIP POWER GRIDUse quick reflexes to connect to the township power grid!  But be careful not to blow that Grid Fuse!  Did you remember to order a spare grid fuse?FEED POWER TO THE TOWNSHIPThe township is hungry for power, so Hydro must be ready to deliver!  In addition, sometimes they'll need a helping hand with delivering peak-load power demands; thus, you'll be receiving 'Township Demands' from the township when there is a power shortageRespond to over two-dozen such demands ranging from mayor press conferences and town carnivals all the way to popular radio shows in the evenings and new factory commissioning events.Ensure your machinery and components are in tip-top shape and manage fatigue levels so that you can stay on-shift for the duration and generate the required power, otherwise you'll miss out on much-needed funding to stay afloat.REPUTATION SYSTEM / NEWSPAPERSAs sole custodian of Hydro, start your career with the full support of the township! However, your shiny reputation rating is in danger of being chipped-away if you fail to make the grade.Claw-back your reputation rating with careful management of the power plant!Your negative actions may land you in the township's newspaper.  Conversely, if you do a good job, you may just hear about it, too.KEEP THE LIGHTS ONYour power station will need its on-site battery accumulators charged so you can keep your own lights on. You'll be leaning on your trusty old generator once again to help make this happen. Accumulators are not endlessly robust resources - they need care - charge them too fast and their 'condition' rating drops, meaning they won't charge efficiently (and in the worst case, will struggle to charge at all).  As you charge the accumulators and run the local services such as power station lighting, you'll be wearing-out the local power fuses which will also need attention...APPLY UPGRADES!You'll be dealing with a lot of antiquated machinery, so by using your 'Upgrade Blueprint', you'll be able to bring the old power station into the modern age (almost), and make it perform better than ever before! WHEN THINGS GO WRONG...
  • Watch that old Generator! It has a tendency to overheat and it may well just catch fire one day if you're not careful.
  • Destroying your generator ends your Hydro career.  Emergency systems like the Generator Fire Control system - if primed and used promptly - might save your generator...this time. 
  • Fail to lubricate machinery and the power station becomes host to a shower of sparks and a cacophony of noises and you may get noise complaints, some with monetary fines attached (but always affecting your reputation rating).
  • Fail to keep the accumulator maintained and it will struggle to take a healthy charge...this will have all sorts of ill-effects on your on-site power requirements.
  • Fail to keep your network of power poles maintained and you'll find your grid output will suffer frequent 'drop-outs' of power
  • Fail to generate sufficient funding and end up in excessive debt and you may find the township treasury department will take a keen interest in your power station and you'll even risk complete power station shutdown.
HOUSEKEEPINGYou're responsible for the keeping the place presentable! Clean windows and wipe up oil stains before the auditor sees...and maybe wipe-off the occasional graffiti tag...CALM DAYS / AUDITORSOn calm river days, perform maintenance like replacing or fixing fuses, cleaning power pole insulators, researching part upgrades, cleaning the air filter, oil stains and windows and keeping the machinery oil levels topped-up.But keep an ear out for the auditor(s)! They'll fine you every chance they get if something isn't quite right.  Some are more strict than others, and some are downright lazy.  Use some creativity to keep them at-bay...SHIPS PASSING IN THE NIGHT Given the bulky machinery and narrow river banks, occasionally-passing ships will need lighting guidance in the form of marker lights along the river bank, which you'll need to maintain and manage.MANAGE YOUR FATIGUEAs the sun dips down towards the horizon, you'll find a sleeping quarters to rest and recharge between shifts. Use the opportunity to address your fatigue levels and start the next shift...maybe take another stab at keeping the township powered-up?DYNAMIC WEATHERWeather effects are completely random and variable and the weather has an effect on your game play in the Hydro world...meaning that Mother Nature can both help (or hinder) you. For example:
  • Rain will soak newspapers but can also help clean certain electrical components like power line insulators.
  • If lightning strikes your power station (or you!), there will be certain variable consequences...
PLAY IT YOUR WAYThe Hydro experience is designed with both casual and 'hardcore' gamers in mind. Adjustable difficulty allows for a customizable experience! Don't like having those auditors on your back? Put them on strike!  Disable or enable noise complaints at your whim, or close the shipping lane and focus purely on generating power. Choose daylight savings so your days are lengthened, and many other settings await your adjustment.(ALMOST) ENDLESSLY-VARIED GAME PLAY!In Hydro, things never go to plan and nothing ever happens the same way twice.  Some fuses might wear faster than others, your oil levels may consume faster sometimes (and sometimes not), supply costs will fluctuate, funding rewards will vary and even Mother Nature will at times throw a curve-ball with its ever-changing river flow speeds and weather conditions.  Maybe you'll get a strict auditor visit and fine you for an errant oil stain you forgot to clean-up...Resting in between each shift (day or night) will randomly generate calm or fast-flowing river conditions in addition to the usual day/night cycle change and weather changes, so no play-through of the game is ever the same!May the waters flow forever fast and your fuses last forever long...

I quite like the sound design and operation. A few things I don't like... The generator should reach thermal equilibrium and it doesn't. I hate this because it makes it near impossible to do anything. I HATE the fatigue mechanic, it goes up way too fast while literally just standing in place. I severely hope that the shift mechanic from the water works game gets back ported to this one. That would be huge! Aside from that, it's pretty dang good. Tutorial broke when trying to fix the fuse so I never learned how to do the ships. I just turned that mechanic off. Wonderful sound design!

An Engineering Dream. Caution, do not load this game on your work computer as you will get nothing done! This game is still being developed by a single Dev and its coming along very nicely. Interacting and LEARNING about all of the old systems is very rewarding once you understand the mechanics. Game Balance and Progression are still a work in progress but I'm having a ton of fun and cant wait for Empire Water Works to come into full swing.

There are decent numbers of job simulators on machine operations and this is one of a niche power plant operator games but a pretty interesting one. Instead of running the advanced nuclear power plant, you are tasked with managing the ancient hydro power station that has its own quirks and challenges. Gameplay is pretty enjoyable and not too complicated even to me who have zero knowledge about this kind of work. You just need to know how to operate it and there are not a lot of things to keep track on. Graphics system requirement is quite heavy. I have to dial down the settings to almost everything outside the texture to avoid blurry texts and be able to run the game at 60 fps. I feel that the game is still a bit lacking but there are features I saw in the road map that are quite promising. I think the game has some potential and rooms to improve. Overall, it's worth the recommendation from me.

OK. This game is not for the faint of heart when it comes to challenges. This game will test your time and resource management to its limits. I walked out of the game with a headache and an addiction to pushing pixies across digital powerlines... THAT SAID, this game IS a niche title and has a few indie game idiosyncrasies. For example the fatigue system is hard to work around initially and keeping track of everything is maddening at first. So if you DO get the itch to produce power you can turn off bits of the games challenge so you can get a handle on the mechanics one at a time in the difficulty settings. it isn't explained in game but it IS explained on the store page. You have 2 shifts, day and night shift with different challenges.
