New content lands constantly - which brings us to:
YOUR CARDS BECOME YOUR POWERS
Every deckbuilder gives you a hand of cards, in Tower Petroleum they get installed on turrets and revamp them. Hero cards are dragged onto turrets and stay there: one hero per turret, each with a passive aura and an active ability you fire on cooldown. Ignition auras that burn the path. Overloads that triple a turret's damage. A loan shark hero whose interest compounds. Your crews decide the run.
MODULES, FOR GOOD
Module cards are installed straight into turrets, they don't expire. Ricochet makes shots split into the crowd. Frost Tech lets hits freeze. One module pays out bonus damage for every petroleum you haven't spent yet, so building a big bank is its own weapon. Same turret - different modules - different results.
A DECK YOU ASSEMBLE BEFORE THE RUN
Each hero carries a card deck you construct before embarking, drawn from everything you've unlocked. Between waves you draft more. Every card you play feeds its domain, Engineer, Elemental or Economics, and that domain grows stronger for the rest of the map. Playing your deck is building your build.
GO FIND THE BROKEN BUILD
The systems are built to be exploited. Usury multiplies a turret's damage for every debt you carry. The Wanderer pays out per nearby turret with no ceiling: swell his aura with Area Amplifiers, pack the whole board inside it, watch it destroy everything. Shocked enemies take extra fire and cold damage. Mimic replays your last card at its own price, and Catalyst makes the copy come out fully upgraded. Find your combos.
BUILD THE DEFENSE
Monsters crawl from the frozen depths along fixed paths. You build turrets on the map, upgrade them, and launch waves at your own pace. Inspect what's coming, plan the round, pull the trigger. Classic tower defense.
ROGUELIKE CHALLENGE RUNS
Pick a hero, pick your pain: Hard, Ruthless or Impossible. Procedurally generated maps and one-choice intermissions between them. A run is a heist: your hero, your deck, your turret loadout -- against whatever the ice brings.
LOSE THE RUN, KEEP THE PROGRESS
Failed runs still bank mastery toward your heroes and card unlocks. Upgrade points buy permanent perks across three branches: Economy, Firepower, Command. Forward Scouts preview the next wave. Warlord stacks permanent damage on your best turret. Carry Over pays interest on wave income. Every run, even the failing, makes the next one sharper.
A CAMPAIGN WITH TEETH
A comic-book story across a world that drowned in snow, where petroleum towers are the last warm places left. Along the way it will put a dying man in front of you and ask for a decision. Your hero branches Good or Evil, and the cards follow. Wishlist to see where the choices lead.

Tower Petroleum Playtest update #6 - patch notes (Tutorial is here)
Greetings, wanderers! The Tower-Defence Fest is done, we have reviewed the feedback that we have received from people who played our game and are back with a new potion of updates. All of these would occasionally be propagated to the Demo version, but we release them in Playtest first.We have implemented the short tutorial to get people acquainted with some non-obvious elements and features of the game. This would be played once when you start a new save, you would be able to replay it from the main menu afterwards.All tower sprites got a little bit of color, to bring some joy into crushing monsters in the frozen wastelands.Cards also received some fresh up, this should make different card types be more easily distinguishable.A number of other artistic improvements: shader effects here and there, new icons for tags, updates for comics panels.Modules that deal damage (e.g. Lightning Strike, Flame Core) would now have a respective damage type (physical/elemental).Another step into UI polish: show more monster details in the wave details, hopefully this would help you counter monsters better. Clean up of the stats panel for the turrets, a bit of elements alignment improvements, use Steam Overlay for external resources where possible.Added graphics settings to the Options screen: dynamics lights and post-proc effects can not be turned off, dynamic resolutions also implemented -- this should help the game run smoothly on low-end machines.Of course a number of bugs crushed, most notable:fix an occasional crash when using the Corpse Bomb Implant cards;fix for the game not closing properly and Steam showing it as still running;fix the Chain Laser turret not actually drawing the lightning bolts, but still damaging the enemies;Mass Upgrade ability fixes: when it won't upgrade turrets if you have 1 or 2 of them, or not upgrading turrets that are above the 4 level;Better camera controls: avoiding jittering on move and zoom;A few UI and UX fixes for the round lose/win screensPla...Read full article on Community Announcements (fartik)AnnouncementsOfficial
