Shotgun Farmers is a first-person shooter that's not only good fun, it's also rather innovative with how you collect ammo and weapons.
When you shoot, if you miss and hit the floor, your missed bullets will end up growing new weapons/ammo for anyone luckily enough to run by and grab it. It's such a simple yet genius idea as it works so well! It's also good for a pretty wide audience, since it's quite a colourful and inviting game so both myself and my Son have enjoyed many hours in it.
It just recently left Early Access with a new update to add in another map, a new weapon and if you play 50 matches in the first week since launch you will get a special cosmetic set to wear. That's another point I like about it, no in-game purchases as all cosmetic items are earned just by playing the game.
Speaking about the release, the developer said very clearly that they're not finished. They have plenty of plans to release some free post-launch content so it's going to continue to grow.
Sadly, it doesn't have a big following so there's not many people playing it online. The all-time peak is only about 76 people but that's not a big issue in this case as it also has bots. These AI players are actually reasonably decent too so it's still enjoyable. The developer is responsive to feedback too, as they actually expanded the practice mode options at my request.
Annoyingly, the Linux version has no fullscreen support so you do need to play it in a window. Other than that, I don't really have any issues with it.
