Ugh, who else has been there? You're deep into Der Eisendrache, trying to upgrade your bow or progress the Easter Egg, and suddenly that crucial computer just... won't turn on! It happened to me more times than I can count, and it's incredibly frustrating when you're trying to achieve those high rounds or nail the Easter Egg. First things first, let's cover the basics. Is the power on in the Undercroft? You know, the main power switch near the church. It sounds obvious, but in the heat of a Zombie Elimination spree, it's easy to miss. Make sure all the generators are active, especially the one that powers the Undercroft area where the computer for the bow upgrades is located. Without power, that screen will stay stubbornly blank. Often, when people say the computer 'won't turn on,' they're referring to the terminal used for upgrading the bows, right? This isn't just a switch-on process; it's part of a specific sequence for each elemental bow. Here’s what I always double-check: Have Your Bow Charged: Are you sure your bow is fully charged with its elemental arrow? For example, for the Storm Bow, you need to shoot the blue orb near the Dragon statues and collect souls. For the Wolf Bow, you need to collect the wolf heads and place them. The computer won't interact if your bow isn't ready for the next phase, no matter how many Zombie Critical Kill shots you land. Correct Location: You need to be at the specific computer terminal in the Undercroft. There are a few screens around, but the main one for bow upgrades is usually against the wall, often near the 'Pyramid Room' entrance. Interact (Hold Square/X): Once your bow is ready and you're at the right computer, you should see a prompt to interact (usually 'Hold Square' on PlayStation or 'Hold X' on Xbox). If this prompt isn't appearing, that's our real problem. Now for the really annoying stuff – when you've done everything right, and it still seems like the computer is dead. These are some troubleshooting tips that have saved my runs: Player Position: Sometimes, your exact position matters. Try moving around slightly in front of the computer. I've had times where being just a tiny bit off prevented the interaction prompt from showing up. It's like the game wants you to stand in a very specific 'sweet spot.' Server Lag (Online): If you're playing online, a bit of lag can delay the prompt. Give it a second, or try backing away and re-approaching. Sometimes, the game just needs a moment to catch up to your actions. Did You Complete Previous Steps? This is crucial for Easter Egg hunters. Is your current step actually to interact with the computer? For example, if you're doing the Wolf Bow, have you collected all the wolf heads and placed them correctly? The computer won't 'light up' if you're not on the right step of the quest. I remember once I spent ages trying to get it to work, only to realize I missed a small detail earlier in the quest! Talk about a facepalm moment mid-Zombie Elimination! Restart the Round: In rare cases, especially after a particularly intense critical kill streak, a round change can sometimes reset minor glitches. Finish the current round, let the next one start, and then try again. This often clears up minor script issues. Game Restart (Last Resort): For really stubborn issues, especially if you're solo, sometimes a full game restart is the only way. It sucks, especially if you've already had a massive Zombie Critical Kill count and a high Elimination total, but better to reset than to be perpetually stuck and unable to progress. Don't let a seemingly 'dead' computer ruin your Der Eisendrache run! Most times, it's a simple missed step or a positioning issue. Keep slaying those zombies, pay attention to the quest steps, and you'll get that computer working in no time. Happy hunting!
