Hey everyone Frog overlord here!
Are you looking for another world to explore? Or another story to conquer? Well at Frog HQ we have you covered.
Mythos Rising...
It's 1939 and the threat of war is greater than ever, but at home a different battle rages on. Dark beings and ancient forces have passed through the veil crossing into our reality. The sanctuary of life as we know it will be over if this epeidemic is not stopped. Cultists, acolystes and the wicked beasts themselves all hell bent on stopping you.
Who are you? The only who can stop this.
A private investigator from the Midsummer Institute. A place where individuals gather and train to risk their lives against the creatures from beyond.
Do you have what it takes?
The game itself uses a 56 card deck which can either be played via the custom bespoke available or by using a standard playing deck. Splitting the cards into various decks you must uncover Clue cards and hunt down opponents to find out more information before you lose your sanity.
As the turns progress you must keep track of the sanity table or be more at risk of developing phobias, delusions or losing your mind completely. Each consequence impacts your character through stat reductions and/or NPC events.
Sinners
The Tower, a magically sealed prison that reeks of corruption and evil. Today's your first day. Thugs, mercenaries and former assassins all stalk the halls carving up terrority for themselves. It's the worst of the worst in there so be sure to keep an eye out or fear losing it..
It's not all bad though. It is rumoured the cursed Princess lives inside, falsely accused and disowned from her family she remains locked away. Finding her might make this sentence easier a friendly face is always needed.
Goodluck! Fresh meat is always the first to go.. especially when Cannibal Bob is around...
Sinners plays closer to a roguelite game. Defeating opponents and completely NPC quests nets you bonus rewards that come in the form of: New weapons, stat boosts, unique armour and special items. These are key for the end game objective.
You will draw 1 location card per turn in which you must choose to draw a Prisoner card or Event card; afterwards gain your rewards and repeat. Once the location deck has been exhausted you will randomly draw 1 End villian & 1 End location - They both have special skills that majorily impact traditional gameplay.
Best be geared up and ready for action to become the Tower's next top dog!
Final Quest 1 & 2
At one point you were adventurers, heroes for hire, feared warriors.
Now you were prey, to be hunted, by the beast the shakes the Earth. A quest had spiralled out of control. Your mission - Journey into the caverns of Mourne and slay the beast. But, you never made it that far. Your last memory was of the overwhelming number of lurkers cutting you and your party down, the pain was unbearable.
Then you woke up...
Making it out of the cave you barely recognise the scenery around you. A woman greets you her name is Fiana she's been waiting for 5 years for your return.
What has happened to your family? Why did you come back when everyone else died? Who is Fiana?
Final Quest 1 takes place inside the Caverns of Mourne. Your resurrection and fight against the beast.
Final Quest 2, In your wake a war has broken out across the land. This Fiana woman needs your help for one final quest...
Both games build a deep and rich history through card descriptions, NPC side quests and various opponent factions. Using traditional RPG systems you must roll up your character choosing a background class and starting equipment plus if your up for it, harness some magic.
The game takes place in 3 sections - Morning phase - Card phase - Evening.
Morning: Roll on the weather and daily event table. These results will change how the cards react and potentially alter the rewards gained.
Cards: Drawn down on the main deck and resolve encounters.
Evening: Your characters get hungry and have to eat. Choose to either hunt or fish and depending on the quality lose/gain stat boosts for tomorrow.
We also have two one more coming soon with its campaign wrapping up in November 2025 - Star Marshal!

Until next time I'll see you on the battlefield,
