Welcome to Fatal Experiment 2.

• This is an early build. 17 levels are currently available. Please report any issues you find to Project Zaero#9999 on Discord.

Features:

• 8 Campaign Expeditions: Experience the storyline in Fatal Experiment 2. Expeditions may last over an hour and will challenge your team.
• 9 Bonus Expeditions: Arcadey / challenge levels. Typically 10 to 40 minutes, these levels are to-the-point and get you straight into the action. They vary drastically and offer a wide variety of experiences.
• 30 Custom Guns, 2 Custom Melees and heavily modified default melee weapons. 4 guns and 1 tool are level specific.
• 13 Classes to pick from that evolve over the course of an expedition by earning XP from kills and assisted kills.
• Many enemy variants with different abilities such as grappling, bleeding, knockback melee, and more.
• Greatly improved gunplay over the original Fatal Experiment.
• Custom Palettes that are painful to look at.

Good luck down there.

Release Notes:

V0.8.8

• Act 3-2 "Crystallized" adjustments.

• Fixed a typo in objective text. Added 60 seconds to the surge timer to add leeway for a rough start.
• Fixed an issue where a Team Scan was actually a Solo Scan. It is now actually a Team Scan.
• Fixed an issue where Becky The Immortal could spawn during the final alarm instead of The Patriarch.
• Fixed an issue where the final alarm would only spawn one boss.
• Fixed an issue where the reactor's final wave would cause Persistent Alarms indefinitely. They are now Persistent Alarms with a Limit of spawns.

• Enemy Changes

• Crystalline Enemy HP nerf. These enemies are generally very tanky, inflict bleed, grapple, and do not stagger. Their crit multiplier is also entirely dependent on your gun, making it unrewarding to score crits. Their health has been toned down slightly to make them more fair to non-damage classes. Striker 55 -> 50, Brawler 99 -> 90, Charger 83 -> 75, Frank 330 -> 300, Shooter 69 -> 60, Sidestepper 88 -> 80, King 3000 -> 2750

• Misc. Changes

• Fixed medkits in 4-2.
• Added a bandaid fix for edge cases where melee would leave enemies at 0.0001% or less HP instead of killing them.
• Reduced Veil projetile count again as they still severely hinder performance at times. Their projectiles now move much faster and deal more damage.

V0.8.3

• Melee Weapon Adjustments

• Added "Sword" melee weapon. Specialized in high base damage with no added multipliers (stagger, precision, back, stealth).

• Added the DeadBodyFix plugin so you waste less ammo.
• Added the ResourceHelper plugin to fit the faster pace of most of Fatal 2.
• Veil performance improved again.

• V0.8.0 Is a stable build with significant balance changes with full access to the first 3 tiers of expeditions as well as both Act 4 expeditions. Builds prior may not be stable and are not recommended. Full detailed patch notes for early versions can be found in the files. Some builds are known to be broken; play 0.8.0+ for a stable release.
