How to get Submachine Gun in Icarus Update
If you've been itching for a new weapon in Icarus that can spit bullets faster than a storm rolls in, you're going to love the submachine gun from the Week 173 update. This bad boy replaces the old light automatic carbine and keeps things rapid and fun. It's got a fresh vibe, uses 9mm ammo, and is now one of the most reliable go-to guns for fast, close-quarters fights.

Find the submachine gun in the tech tree
First things first, the submachine gun sits in Tier 4 of the tech tree. If you already had the light automatic carbine unlocked before this update, surprise - it’s already been replaced by the submachine gun. If not, scroll to the upper part of Tier 4 and look for it among the other firearms. It’s placed pretty close to the assault rifle and has a similar silhouette, so don’t get them confused. It’s an easy unlock with the usual points if you’re already at that level, so make sure you've progressed far enough before searching for it.

Craft requirements and materials
To actually make the submachine gun, you'll need a fabrication bench and a good stash of titanium. The recipe calls for 10 titanium ingots and 10 titanium plates. Yep, it’s a bit pricey, but the good news is that it pays off long term because of its insane durability. Also, you’re going to need 9mm rounds to feed this beast, which are now the same ones used for pistols. You can craft them from Tier 3, and they’re super cheap compared to rifle ammo, making this weapon budget-friendly for extended fights.

Weapon stats and feel
This gun is all about speed. You’re looking at a fire rate of 400 rounds per minute with a 20-round clip and a super quick 3.2 second reload. It’s like a buzzsaw - once you pull the trigger, it just shreds. Now, don’t expect sniper-level accuracy. It kicks and bounces a lot, especially during sustained fire, so it’s best used up close or in mid-range fights where precision isn’t everything. It also has -75% crit damage, meaning headshots and weak spots won’t hit as hard, but you’ll make up for it with the sheer number of bullets.

Compared to the new assault rifle, the submachine gun is faster, cheaper to run, and more forgiving if you miss a few shots. The assault rifle hits harder but has fewer rounds and a slower reload. If you’re running into tight caves or swarms of enemies, the SMG shines. During testing, it pulled off about 100,000 damage per minute, putting it just under the assault rifle's 120,000, but still way above most other weapons like the hunting rifle and trench shotgun. It also lasts longer in fights thanks to three times the durability of the old carbine.

Best situations to use it
The SMG is ideal when you're in fast-paced battles where enemies close the gap quickly. Think base defense, animal rushes, or quick movement fights in caves. The high rate of fire lets you react fast, and the low ammo cost means you won’t run out as quickly as with rifles. Use it when you’re on the move, when aiming fast is more important than aiming perfect. And don’t forget - it’s got a single attachment slot, so slap on a sight or recoil reducer if you can.
Ammo efficiency and reloading tips
One of the nicest perks of the SMG is that it eats pistol ammo, which is easy and cheap to craft. You won’t have to sink crazy amounts of materials into each fight. But because of the fire rate, you’ll still go through a ton of bullets, so it’s smart to always carry backup stacks. Reload time is quick, but during long fights, keep moving between reloads or use cover because those few seconds can be deadly if you’re swarmed.

Craft your first SMG
So now that you’ve unlocked it and got the mats, craft it up at your fabrication bench. Once it’s ready, load it with 9mm rounds and give it a test. You’ll immediately feel how light and fast it is compared to the bulkier weapons. Try it out in a safe area before you take it into a big fight, just so you get a feel for the recoil pattern and spread. It handles a bit wild, so practicing bursts helps.
If you were using the light automatic carbine before this update, congrats - it’s now the SMG. The swap was automatic, and any old carbines in your inventory are now submachine guns. That means you can dive right into testing it without spending extra unlock points. It’s a nice upgrade, with better durability and a slick new feel, even if the crit damage got toned down.
Always stay mobile while using it. Aim for the chest and let the spread work for you. If enemies cluster, go full spray mode. If you want more control, try short bursts and step into your shots to manage the recoil. It's not great for long-distance targets, so pair it with a hunting rifle or bow if you're trying to cover all your bases.
The new submachine gun in Icarus is fast, reliable, and an absolute ammo-efficient machine. It doesn’t deal massive crits, but it makes up for that with speed, durability, and cost-effective firepower. Unlock it, load up, and let the bullets fly.
