Alien Invasion Event
The Alien Invasion Event introduces extraterrestrial enemies that spawn randomly across the forest map via crashed UFOs. These sites, marked by glowing green beacons visible at night, are high-risk zones where players can engage aliens and loot rare resources. Aliens (2–5 per encounter) scale in difficulty: pre-Day 50, they use basic energy weapons; post-Day 50, they wield advanced tech with higher damage. Crash sites contain 2–4 lootable containers and a teleporter, which requires a Power Cell to access the mothership. Aliens drop Alien Shards, essential for crafting new items.
New Classes: Alien and Cyborg
The update adds two classes to the existing seven, each leveraging alien technology for unique playstyles:
- Alien Class: Designed for players who want to master alien tech, this class offers high-risk, high-reward gameplay. Its Plasma Rifle deals consistent damage, while the Holo-Map aids exploration. The Nano-Skin and perks like Tech Affinity and Overcharge make it ideal for crash site runs. The Evasive Teleport provides a tactical escape option.
- Cyborg Class: A durable, hybrid class combining human and alien tech. The Cybernetic Arm boosts melee combat, while the Energy Shield and Reinforced Frame perk enhance survivability. The Fusion Core doubles as a weapon and crafting component, and Regenerative Circuits ensure longevity in prolonged fights.
Both classes are unlocked with Diamonds, earned via chests, badges, or surviving Day 99.
Xenology Badge
The Xenology Badge is a prestigious achievement earned by defeating the Mothership Core, a 1,000-HP boss with energy blasts, drone swarms, and EMP pulses. Accessing the mothership requires a Power Cell and surviving its hostile environment. Rewards include 200 Diamonds, Xeno-Warden Armor, and the Mothership Blueprint for crafting the Quantum Disruptor. The badge is repeatable, with scaled-down rewards for subsequent clears.
UFO Crash Sites and Mothership
- UFO Crash Sites: Spawning every 3–5 days (up to three active), crash sites are guarded by 3–6 aliens and contain lootable containers. Radiation (1 DPS) affects players without protective gear like Xeno-Warden Armor. Loot includes Alien Shards, Power Cells, Plasma Grenades, and Nano-Repair Kits.
- Alien Mothership: A dungeon with randomized layouts, zero-gravity zones, and elite aliens. Players face laser traps and tougher enemies for rewards like Quantum Cores, Alien Data Chips, and Gravity Boots. The Mothership Core boss is the ultimate challenge, dropping high-value loot.
