Control 2 Wiki: Ultimate Items & Equipment Guide for Altered Items, Collectibles & DLC
Master Control 2 with our wiki guide: ability upgrades, altered item locations, collectible spots, and DLC walkthrough. Expert tips for every item type.
**Key Takeaways**
Control 2 introduces 37 altered items with unique effects—learn where to find the best ones early.
Collectible locations span 12 major zones; we highlight the 5 hardest-to-find ones.
DLC walkthrough covers both "Foundation Echoes" and "The Threshold" expansions, with boss strategies.
Ability upgrades cost source points; prioritize Shield Bash and Launch Efficiency for combat.
**Thermos of Infinite Coffee** (Research Sector, break room on floor 2): Restores 30% energy instantly. Cooldown: 45 seconds. Essential for flight-heavy puzzles.
**Floating Paperweight** (Executive Sector, desk in Director’s office): Increases Launch damage by 15% while held. Stacks with other Launch mods.
**Malfunctioning Stopwatch** (Maintenance Sector, behind the boiler): Slows enemy projectiles within 5 meters by 40%. Perfect for the DLC bosses.
**Pro tip**: Altered items don’t appear in your inventory. You carry them physically. Drop them only when you’re sure you won’t need them—you can’t retrieve them after leaving the zone.
### Ability Upgrades: What to Prioritize
Your service weapon and powers level up with source points (earned from missions and hidden caches). Here’s my recommended order based on difficulty spikes:
1. **Shield Bash** (level 2): Costs 3 source points. Knocks back shielded enemies. I used this against the Hiss Commanders in the DLC—saved me 20 minutes of kiting.
2. **Launch Efficiency** (level 3): Reduces Launch cost by 25%. With the Paperweight, you can spam debris for 40% less energy.
3. **Evade Distance** (level 2): Doubles dash range. Critical for the maze-like Threshold zones.
Avoid upgrading Seize until late game. The Hiss thralls in Control 2 are weaker, so it’s less effective.
### Collectible Locations: The 5 Hardest
There are 142 collectibles total (documents, recordings, hidden caches). Most are straightforward, but these five will test your patience:
| Collectible | Zone | Notes |
|-------------|------|-------|
| Director’s Diary #4 | Research Sector, behind a false wall in the astral lab | Requires Levitate + Seize to open the barrier |
| Altered Item: Mirror Shard | Executive Sector, in the janitor’s closet (only accessible after completing “Threshold Echoes” mission) | Hidden behind a painting |
| Recording: Dr. Darling’s Final Log | Maintenance Sector, inside the furnace (must extinguish flames with shield) | Timer: 30 seconds before burn damage kills you |
| Cache of Source Points | Foundation DLC, in the cave behind the waterfall | Requires the “Slow Fall” upgrade to reach safely |
| Hidden Trophy: “Oldest House Key” | The Threshold, final room after the optional boss | 1% drop rate from the Fractured Echo |
**My opinion**: The Mirror Shard is the most frustrating because the mission trigger is easy to miss. Don’t skip side quests in Executive.
### DLC Walkthrough: “Foundation Echoes” and “The Threshold”
Both DLCs add new altered items, abilities, and a 3-hour campaign each. Here’s the streamlined path:
#### Foundation Echoes
Objective: Repair the Foundation’s core by collecting 4 crystal shards.
First shard: In the Cavern of Echoes. Use Levitate to cross the gap; watch for falling stalactites.
Second shard: Behind the locked door in the Hall of Records. You need the “Resonance Key” from the side quest “Echoes of the Past.”
Boss: The Echo Entity. Strategy: Stay mobile, use Shield Bash to interrupt its beam attack. Weak point is the glowing chest. Took me 3 attempts.
#### The Threshold
Objective: Open the door to the Oldest House’s origin.
Key item: Fractured Mirror (find in the Astral Plane after defeating 3 Hiss Wardens).
Puzzle: The room with shifting platforms. Solution: Follow the red light sequence (left, forward, right, forward).
Final boss: The Fractured Director. Phase 1: dodge lasers. Phase 2: Seize the floating debris to create cover. Phase 3: spam Launch while evading. I used the Thermos for energy sustain.
### Mods and Equipment Upgrades
Mods are now tied to your service weapon’s form (Grip, Shatter, Pierce). Each form has 2 mod slots. Best combinations:
**Grip (all-around)**: Damage +10%, Accuracy +15%. Found in Maintenance Sector caches.
**Shatter (close range)**: Rate of Fire +20%, Ammo Capacity +30%. From Foundation DLC reward.
**Pierce (sniper)**: Zoom Stability +25%, Critical Hit Chance +10%. Hidden in The Threshold after the puzzle room.
**Don’t** waste mods on Seize range. It’s never worth the slot.
