I'm a really big fan of what you've done here. There aren't too many ttrpgs centered around small unit tactics but this executes on that premise so elegantly. The lethal 1s mechanic is a perfect way to convey the random brutality of its subject matter and giving the player the ability to buy out of it with successes (that they really need elsewhere) is a mechanically interesting way to push the players into throwing bodies at the problem like a bonafide World War 1 General while keeping them on the hook for their actions. 

The cards are a great way to add randomization and replayability while keeping the cognitive load to run the thing pretty low and manageable. 

As a document the game is really well explained, which is highly appreciated given how many departures it takes from a baseline havoc engine game. I don't often see examples of play written into game jam games but they're a great way convey how the whole thing works in motion.

Overall a lot of very cool ideas, this seems like it'd make for a very unique mini-campaign, or would a great set of mechanics to tinker into an XCOM hack or something like that. 

nice production and good to see more WW1 games.  Looks like it will play well and be pretty grim as the setting is. Be interesting to add some of the horror elements of EtR or other dark horror in the trenches. 

As another commenter mentioned, using the Havoc Engine objective system to represent the fog of war is a sharp choice and helps sell the grittier, more grounded fiction you're gunning for here compared to Eat the Reich. I think your other mechanical choices support that fiction well, with the lethality die slowing the crawl towards each objective being a standout choice towards achieving the senseless hostility and slogging pace of trench warfare. 

The visual design choices definitely help sell the fiction, but I found large blocks of typewriter text a little difficult to read at times. I'm definitely interested to see the VTT stuff you've set up when the links are ready to fire!

For starters, the presentation is fantastic. The scope is also impressive. The card system seems pretty well thought out and I'd absolutely be interested in giving it a shot. Building the Havoc Engine objective system into a fog of war card that gets progressively revealed is both thematically interesting and feels like it would allow for this to be replayed several times showing the different ways war can play out. 

Implementing the "lethal" roll to demonstrate the brutality of war is a great idea. It goes against the grain of the havoc engine's premise that you play as larger than life killers by making your characters replaceable, but that helps to drive the theme. I do wonder if that impacts your ability to connect with a specific character and roleplay their emotions and actions, but I think adding the Regroup actions/cards helps to alleviate that issue. I wonder if it would make sense to have a Mourn regroup action (or a subaction contained in Gossip) in which the characters can acknowledge those killed in the previous battle phase. 

Another bit that I really liked was the "trench gong" promotions. What a great way to work in a bit of history into a mechanical element of the game. 

As a final note, the choice to make this a game about struggling to achieve seemingly random objective passed down from on high, rather than giving the players a discreet objective to accomplish and all the tools they need to get it done is definitely thematically appropriate and interesting. I really enjoyed reading through the document and would be happy to give it a try sometime.
