FTL: Faster Than Light is categorized as a Rogue-like game, because events within the game are randomly generated and you start each game from scratch. At the start of each game, you choose from one of many available ships. Each ship has a different layout, different equipment, and different starting resources. The only consistent feature of the Slug Cruiser class of ship is a complete lack of a sensor system. Since slugs are telepathic, you can always see where enemy crew members are and slugs specialize and kill enemy crew in various ways. In general, you will want to stick to nebula while using a Slug Cruiser and upgrade your reactor early to deal with the many plasma storms you will run into. The following guide to the Slug Cruiser ship class in FTL: Faster Than Light will help you obtain each variant of this ship and use them efficiently.
Variant A: Man of War (16 Fuel, 15 Missiles) – The Man of War has an impressive array of weapons, but doesn’t have a powerful enough weapon control system to power them all at once. Until you upgrade this, you will be reliant on your Dual Lasers to win battles. Once upgraded, you can start using your Anti-Bio Beam and Breach Bomb I to kill enemy crew without destroying ships. You only have two crew members, so you need to be very wary of any encounters where you can lose crew. Your early priority should be getting new crew and upgrading your weapon control system. Your weapon combination can actually win battles for you without any additions until roughly sector 5, so feel free to prioritize other upgrades early. Battles with this ship tend to complicated, and you can’t rely on autofire, but you have a very strong set of weapons for so early in the game.
Unlock – The Man of War is quite easy to unlock. You need to get a ship to the Slug Home Nebula sector that has level 2 sensors. While fighting a Slug vessel, it may try to surrender. If it offers you a prototype weapon, refuse the weapon and you will get a quest marker. At the quest marker you need to choose the option to tail a ship. This will give you the option to maintain lock from a distance, which will lead to a fight. Win the battle and you unlock the Man of War. It is a lot of steps, but all the steps are easy. Alternately, you can try to defeat the rebel flagship with a Mantis Cruiser ship. This is really hard. If you do try it, use the Basilisk or the Theseus, which are the best ships for that endeavor.
Variant B: Stormwalker (16 Fuel, 25 Missiles) – The Stormwalker is insane, because it is almost entirely reliant on missiles. If you run out of missiles, you basically can’t fight at all. The ship has three Slug crew, a crew teleporter, an Artemis Missile, and a Healing Burst. You can either fight ships by launching Artemis Missiles or you can teleport your crew to the enemy ship and then keep the crew healed with Healing Burst. The latter is insanely risky, but since you don’t have a medbay, it is the only way to heal your crew members. The layout of this ship is terrible, both for putting out fires and for repairing systems. The only minor advantage this gives you is that enemy boarders move around slowly, especially since you have security doors to start. Your first priority for this ship has to be getting a weapon that doesn’t require missiles. You simply can’t afford to be spending multiple missiles in every battle. You probably want a medbay, too, because relying on the Healing Burst is way too risky. The Artemis Missile will serve you well for the majority of the game and Slugs are a great race in general, but even with those advantages, the Stormwalker will take all your skill to win a game with.
Unlock – The Stormwalker is unlocked by completing 2 of the 3 Slug Cruiser Achievements.
Variant C: Ariolimax (16 Fuel, 1 Missile, 15 Drone Parts) – Ariolimax is loaded for bear and actually quite effective. It starts with the Chain Burst Laser, which is a nice weapon in longer battles. Alone that weapon can’t break through a shield and defeat an enemy ship, but that is why you have hacking and mind control systems. Use mind control on the enemy in the shield system and you can let the enemy crew destroy the system for you. Alternately, at the cost of a drone part, you can disable any enemy system, including shielding. You want to upgrade mind control and hacking early to really take advantage of these two systems. You will usually use one drone part per battle on hacking, but that isn’t too bad. The amount of scrap you save on not having to buy these systems more than makes up for the drone parts you will need to buy eventually. If your ship has any flaws, it is that you rely on a clone bay and most of your systems are in nearby proximity to each other, but that shouldn’t be a huge problem. Upgrade your door system early to protect against boarders and keep your shields upgraded to protect against beam attacks. This isn’t as easy a ship to use as a Kestrel or Federation Cruiser class, but it is a lot of fun.
Unlock – You need to reach sector 8 using a Stormwalker to unlock this. There is no easy way to do this other than try a lot and probably buy a lot of missiles. The Stormwalker is one of the more difficult ships in the game to use.
Slug Cruiser Achievement: We’re In Position! – This has to be the craziest achievement ever. In order to acquire it you need to have vision of every room on an enemy ship without having functioning sensors. Since you can only see rooms that your Slug crewmember is in or adjacent to, you need to find a very small enemy ship. If you manage to acquire two extra crew members in sector 1 and don’t mind committing suicide with them, you should be able to pull this off on a sector 1 enemy.
Slug Cruiser Achievement: Home Sweet Home – You need to jump your ship into 30 different nebula beacons before your ship reaches sector 8. You can basically determine whether or not this is possible as soon as you complete sector 1. If the map includes a path where you can enter at least three nebula sectors, this should be possible. If not, reset and try again.
Slug Cruiser Achievement: Disintegration Ray – To acquire this achievement, you need to kill three enemy crew members with a single shot from your Anti-Bio Beam. This is challenging, but not impossible. You need to find a ship that has two features: at least three crew members and no medbay. They do exist, so this isn’t impossible. Then damage the enemy crew members with Small Bombs. Each Small Bomb does 30 damage to an enemy crew member and the Anti-Bio Beam does 60 damage. Once each crew member is at 60 health or less, knock out the shield with a shot from your lasers and then swipe the beam over all three targets.
