Location: Level 1.3 (Main Drainage) The Secret: The Toxic Waterfall. How to find it: Midway through the level, you see green toxic waterfalls. Most players avoid them. Equip the Environmental Suit (sold in Act 1 shop). Walk directly into the center waterfall on the east wall. You will pass through it. Inside is a small cave with a dead scientist and a respawning loot crate. Top Reward: Every time you leave and re-enter the cave, the crate respawns credits. (Fixed in v1.2, but still works in Reloaded base version). Collect ~500,000 credits here.
Location: Level 2.5 (Bio-Dome) The Secret: The Unmarked Elevator. How to find it: In the center of the Bio-Dome is a giant tree. Behind the tree, on the floor, is a discolored grate (grey vs. brown). Shoot the grate with a Shotgun. Drop down. You are now in a secret sub-level filled with "Mutant Runners." Survive for 60 seconds without leaving the room. Top Reward: Boots of Alacrity (+25% movement speed). Speed is the most important stat in bullet hell scenarios. alien shooter 2 reloaded all secret place top
Based on community consensus and gameplay efficiency, the following are considered the most impactful secret areas in Alien Shooter 2: Reloaded: Location: Level 1
1. The Proving Grounds Secret (Military Base – Level 3) One of the earliest and most vital secrets appears in the Military Base. After clearing the initial hangar, players enter a long, east-west corridor with steel containers. The secret is not on the wall—it is beneath the floor. Look for a slightly discolored grate in the lower-middle section of the corridor. Standing on it and using an explosive (grenade or rocket) will shatter the grate, dropping you into an armory. Reward: One full medkit, 500 credits, and a Jackhammer automatic shotgun. Acquiring the Jackhammer before the first major alien nest trivializes the next three levels. Equip the Environmental Suit (sold in Act 1 shop)
2. The Research Lab Vent Shaft (Lab 7 – Level 8) Lab 7 is infamous for its maze-like layout and invisible spider aliens. In the northwestern corner of the main computer core room, there is a row of servers that seem solid. They are not. By hugging the left wall and spamming the interaction key, the player will find a one-tile gap leading to a ventilation shaft. Reward: A Cyber Implant (+20% movement speed) and a full set of heavy armor. Speed is survival in Alien Shooter 2; this implant allows players to outrun exploding aliens entirely.
3. The Alien Hive Queen’s Pantry (Hive – Level 12) Deep within the organic walls of the Hive, just before the first Queen encounter, there is a pulsating membrane that looks identical to every other wall. However, if the player has a flamethrower or any plasma-based weapon, this membrane burns away to reveal a hidden cavern. Reward: A staggering 10,000 credits and the “Ripper” minigun. This secret is considered “top” because it directly provides the best anti-swarm weapon in the game right before the most swarm-heavy boss fight.
4. The Final Escape Secret (Spaceport – Level 15) During the frantic countdown escape sequence, players typically run straight for the shuttle. However, taking a 3-second detour to the left of the final cargo bay reveals a destructible metal panel. Behind it is a lone terminal. Reward: A Master Keycard that unlocks the game’s secret “Mercenary” ending and a permanent +50 to maximum health. This is the only secret that affects the narrative conclusion, making it the most sought-after for completionists.
