You've gotten some seriously good praise on this, but there's also a lot of stuff that's clearly just BS from someone who can't even breath without being told how to do it. So I figure I'll try to clear some of that up instead.

1.) Only commenting on the level design is an insult to everything you did with this mod. Anyone with a brain in their skull knows you didn't make this level, but when all they read is praise on that and then see what I saw, they may be tempted to think all that praise was empty. I'm here to say it is NOT empty. The level is short, (the same length as Sierra-117, longer since you're moving slower) but shows a competent understanding of stealth design that we don't see much these days.

2.) Yes, it's dark. So was Splinter Cell. I don't know how it originally looked, but your lighting is stellar now. Although some glowing bits just to see in the dark, less for illumination and more for aesthetic, would be nice. ODST's engine does a lot to make lights in the dark really pop and taking advantage of that won't hurt. It'd also help guide the players if done right, but it's not like this level is confusing.

3.) If you play it as a stealth game, it is NOT too difficult. It has some parts that are action/stealth, a VERY well done all-stealth section with the drones, and overall just feels more like an experience you have to take slowly and methodically. You did exactly what you set out to do, and that's worth a ton of praise!
