About this game
Get ready for a thrilling and innovative gaming experience with GROSS, a hybrid of tower defense and first person shooter genres. With its fresh and unique mechanics, you'll be hooked from the start as you strategize and defend your way to victory.
In GROSS, you are tasked with defending your base against waves of enemy attackers in classic tower defense fashion. You have the freedom to build barricades and turrets to create mazes and launch attacks on the enemy, as well as place traps on the ground for added defense.
During the construction phase, you can experiment with different combinations of turrets and barriers to come up with the most effective obstacle course for your attackers. And don't worry about time limits or wasted resources - you can sell everything you build for a full refund until the next combat phase begins. So if you love the strategy and satisfaction of building the ultimate tower defense setup, GROSS is the game for you!
Once you are done building your defenses, get ready for intense, fast-paced combat! With a huge arsenal of guns at your fingertips, each featuring different ammo types, you'll have to make split-second decisions to take down waves of zombies. Full metal jacket rounds can pierce through multiple enemies and even objects, while hollow points send foes flying and give you some breathing room. Incendiary rounds ignite zombies and keep them burning, and grenade and rocket launchers can deal massive damage to groups of enemies - but watch out, they may also destroy valuable cash pickups.
In addition to all these guns, you'll also have access to a range of active abilities that give you even more ways to defeat or distract enemies, move around more efficiently, or manage your resources. With over a dozen weapons to choose from, gunplay in our game is always exciting and rewarding. Are you ready to take on the undead?
Money is essential for success. You'll need to gather it from defeated enemies as quickly as possible, but beware - you're not the only one after this valuable resource. You'll need to get it to safety so you can buy defensive structures and active abilities, and it also plays a major role in determining your score.
GROSS keeps you on your toes at all times. Every action you take - or don't take - has consequences. If you focus on taking out attackers while your defenses are overwhelmed, you might turn the tide of battle, but you'll also risk losing precious money that could be used to improve your defenses in the next construction phase. Stay sharp and stay ahead of the game to come out on top!

This patch fixes Unity's vulnerability CVE-2025-59489, which was published a few days ago. Both the demo and the full game have been patched.No new guns or maps in this patch, but at least the code is now once again as impenetrable as a good killbox with a bunch of flamethrowers and machine guns.More information about the vulnerability:https://unity.com/security/sept-2025-01Read full article on Community Announcements (hangry owl games)Community & EventsOfficial

1 year anniversary
Hello everyone! It's been one year since GROSS was released, after being in development for over 18 months. I'd like to take this opportunity to thank everyone who gave this game a try, told their friends about it, gave me feedback, wrote a review or sent me some words of encouragement. Making a game is a huge journey and it wouldn't have been possible without you. For the next two weeks, GROSS is 50% off. If you already own it, it makes an ideal present for in laws, new neighbors or as an ice breaker on first dates. And if you downloaded it from The Pirate Bay, now's a good chance to clear your conscience. What have I been doing lately? One of the most requested features for GROSS has been co-op multiplayer, so I've spent the last couple of months learning the core concepts of networked multiplayer. I don't like learning in a vacuum though, I need to learn with a clear goal in mind. Which is why my learning took and takes place in a new game that I'll release later this year. It's a relatively simple game, combining key elements from Snake and Bomberman into a four way multiplayer game where players can mess with each other in all sorts of ways. I originally planned for this to take a couple months at most, but it turns out building a multiplayer game comes with quite a few challenges of its own. Also, making an AI that allows CPU controlled snakes to find their way out of tricky situations was and is a bit of a challenge. This game will take another couple months. In the meantime I've put a Steam page up for it, so if that sounds like your jam, feel free to add it to your wishlist: https://store.steampowered.com/app/2678860/nope_rope/ Does that mean GROSS will get co-op multiplayer? Alas, no. Turns out, building a multiplayer game is very different from building a single player game. Since GROSS was not built with multiplayer in mind, adding it retroactively would be a huge task. A huge, very painful task. Essentially, it would require writing most of the game fro...Read full article on Community Announcements (hangry owl games)Patch NotesOfficial
Patch Notes 20.04.2023
Bug fixes ATMs that were glooped didn't pick up existing cash once the gloop was gone. Small bug/performance fixes. If you encounter a bug, please report it straight away ingame by pressing F1 and describing the issue. This makes it a lot easier for me to replicate and fix it. If you would like any direct feedback, don't forget to include your email address.Read full article on Community Announcements (hangry owl games)Patch NotesOfficial
Patch Notes 10.04.2023
Hello there, It has been a while since the last update. It's another relatively small patch, but I hope it will make the game a wee bit better nonetheless. Features & other changes Highscores now display the wave that players reached (this only works for highscores recorded with this and future versions of the game). There is now extra score awarded at the end of each combat phase, based on how much health your base has left. The score you receive is 10 * * . A few examples: If your base has 87% health left at the end of the 5th wave, you get 4’350 extra score. Over 10 waves, you can gain a maximum of 55k extra score. Over 20 waves, you can gain a maximum of 210k extra score. Over 30 waves, you can gain a maximum of 465k extra score. The score is awarded right when the last zombie dies and the 10 second grace period starts. The score is added directly to your total score and is not subject to a multiplier. New health bars (better looking, not as cluttery, smaller performance impact). Bug fixes When changing languages, the “Exit game” button did not change its caption (until the settings menu was closed). The collider on the maniac (punk) zombies bomb was bigger than intended when hitting it from certain angles. When you shot at the foundation underneath an ATM with the cash attachment enabled, it didn’t register as a hit against the ATM and didn’t result in depositing cash. This is semi-intended, the foundation isn’t actually part of the ATM. But it’s not very intuitive, so now shooting the foundation results in deposits as well. Cash bullets now are no longer stopped when hitting a hologram decoy. Fixed overkill damage. The damage reported (both visually by the damage numbers and internally for scoring) is now capped to the actual health the enemy has left. Fixed issues with floor textures/models in LAB. Vanguards, when slowed down significantly, were no longer animated (technically they were animated, but the speed was so low that they looked static). When switchi...Read full article on Community Announcements (hangry owl games)
