About Ammossum

The world is falling apart, and your family has been taken from you. The infected swarm the railroads, the plague spreads, and the only way forward is through fire and chaos. Keep the train moving, search for answers, and face the truth waiting at the end of the line.
Why settle for ordinary guns when you can craft pure chaos? Combine and evolve your projectiles—nest them within each other, fuse them into devastating combos, and fill the battlefield with nonstop explosions. The possibilities are endless, and so is the firepower!
Your train isn’t just a ride—it’s part of your build. Each railcar adds unique bonuses, from economy to battlefield control. Pick the right upgrades, mix the synergies, and fine-tune your setup to turn every fight in your favor.
Every run brings discoveries. Unlock weapons, find hidden mechanics, and expand your arsenal with each attempt. The more you play, the stronger—and wilder—your options become. Experiment, and push your limits with each new attempt—because no two runs are the same!

I gave this game an honest try and it was fun in the beginning. However, I just found that a lot of the weapons and effects were either difficult to understand or ended up seeming to do the same thing. You'd often end up with a massive chain of projectiles going out from your weapon with really unclear ideas of whether the later ones would do anything. The characters are all just different starting conditions as well, making it so there's functionally not much difference in playing different characters. The only one I ended up enjoying was the gambler one where you worked with random items each time. Finally, the progression is super odd. I get giving scaling xp at higher difficulties, but the scaling is so extreme. I'm not even at the highest level and it's 500x the xp from playing on a lower level. I ended up just jumping to the highest difficulty because it made no sense to play on a lower difficulty and barely progress. Even my highest difficulty only gets me a level in a complete run. This game has some fun ideas in it, but ultimately it just ended up falling flat for me.

This is a tough one to downvote, especially considering how much I love opossums but in terms of rogues, there just aren't alot of options in terms of builds and unlike some others, including my favourites , you can't really pull off a "1 hp and a dream" moments when your build is sub-optimal as alot of the time, you'll just be mathematically unable to kill the enemies fast enough, alot of runs will end because you just don't shoot fast enough to kill the enemies approaching your train in time, even if you're 1-shotting them and this moment in the run often shows up well before you've gotten a foothold in terms of a functioning build Also, the [spoiler]big beaver[/spoiler] boss is very frustrating and overwhelming to fight against for similar reasons. The few runs I did have ended because the game crashed though this seems to have gone away now. Also, one of the runs caused crashes because i found a build that raised the stats so ridiculously that they integer overflowed stats to -2 billion, though this isn't necessarily the games' fault. This is to date my only successful run.

Legitmately one of the coolest well designed games that couple inventory management, roguelike economy elements, and the crazy ♥♥♥♥♥♥♥♥ of stacking effects. 10/10 game. The things you can do in this game might be overwhelming to some at first but I promise you if you stick around and learn it, you'll fall in love.

First few runs I got slammed as expected. Once I understood what I'm doing made some pretty fun and chaotic builds that shoot one bullet into 15 other ammo types that explode on screen or have my carts that shoot on a cooldown of 0.2 seconds shooting 20 projectiles that spawn more projectiles. I love western style so It's gonna be way more biased for me but I think its definitely a game worth picking up. Once you make it passed the initial learning phase It's a solid rougelike. Currently up to difficulty 6 and the only complaint I have is wishing there were some super op carts to chase feel like everything else is pretty well covered, 8/10

It's a good concept though there are some obvious design flaws and it suffers from a lack of content. For the price it is ok but I don't see it having as much longevity and replay value as Magicraft. For starters the meta progression just gives you a choice from three random upgrades and some are clearly more useful than others. There is essentially no point picking the +10% to bullet/arrow/ball/frag upgrades since it is easy to get these figures into the hundreds or thousands with upgrades in a run. Whereas the +1% to bone drop or crit chance are far more valuable since even in an endless run it is hard to get these figures above 10 or 20%. So when you level up and only get the +10% options it feels like a waste. The meta progression would work far better with points to spend on a build in each run. There doesn't really seem to be any point in going for a crit build anyway however since you will get loaded down with mushrooms that increase and decrease stats at random when melted down and these will almost invariably end up destroying your crit chance and even making it go negative. I don't think I have encountered any aspects or items which boost crit chance which means that al…
