- Cool setting idea, with some neat rooms and concepts
- Holographic escape vehicle is a creative idea
- Lots of buildables around the map
- Low gravity is a great touch.

- Bile being so early on the tree renders all the defenses moot; it can be spammed indefinitely
- Bots can only arm themselves through the "Switch trick", which can be very tedious with weapons and supplies.
- Some defenses require an upgrade, but none could be found
- The map does not seem completable; after building roughly 5 minutes straight I added some to the ship, but an additional 10 minutes of adding happened and no visible progress was made, causing me to give up.
- Last but not least, the biggest problem: There is literally no reason to visit the rest of the map. Only one control terminal seems active, and everything you need is there. The only defenses worth building are those immediately around the control panel as a result - maybe the halls - and then it's best to camp there, get an ammo pile, stack some medkits on the floor and just spam vomit jars indefinitely. With the mob sizes, even tanks fall to this in seconds.

A great starting idea. When I was first looking around the map I found it quite entertaining, with some visual issues being made up for by a neat atmosphere. However, once I found the control area, that was the last I ever had reason to explore the map. I sincerely apologize if there is a reason later in the map, as I typically do not review DNF, but it seemed that I was either making no progress on the ship, or that it required so much time to advance each level it would have been another half hour of vomitjar spamming.

I think there's a lot of potential here. I'd love to see this map repaired. I'd recommend that you move the different tech trees to different parts of the station. If you could only obtain Bile from one wing, and guns from another, and health from yet another? You'd have a hell of a reason to move around your map and enjoy things like the low gravity. Also a more detailed indicator of the progress on the ship would make building it infinitely more clear and satisfying.

Anyway, I'm hoping you decide to improve the map game play! Seriously my biggest complaint is less with the overall map and more than that the way it's balanced, you have zero reason to ever explore or use any of it. And that's a shame as I can tell a lot of work was put into the barricades and such. Let me know if you patch, I'd be happy to increase my final score (which I'll admit gets a slight bonus modifier by my love for sci-fi maps.)

- A hybrid building/scavenge system
- The map forces you to be proactive and not camp
- Difficulty seems in the sweet spot
- A smart move making bile and pipes rare, giving you only the molotov! Bile is a life saver on this map.
- Forcing players between purchasing items and funding their escape route adds depth.

- Some items seem priced too low; unlimited defibs for 3 makes things far easier than they would be otherwise
- The defensive structures only occasionally feel worth constructing
- Gas cans can be permenantly destroyed in accidents, but piles do not regenerate, which can render the map unwinnable in a disaster
- The bots like to jump off the really tall stuff to their doom frequently - some landings to break the fall could be helpful!
- Bots cannot use the gear acquiring buttons, forcing you to buy a second item to toggle and "drop."

So far of all the other Let's Build maps I've gotten a chance to check out today, so far, my favorite bar none is this one.. there's a few quirks here and there (The SIG won't be active unless you have modded or used a change level, for example, making the most expensive item shoot blanks) but overall, I definitely had the most fun with this one.

Smart design decisions encouraging a proactive role in building your escape is a huge help. I was able to play the map fine with bots by using the "Buy an AK47, then buy an Uzi so you can toggle and drop them" route, but it made things rough. If you could make the items appear/drop instead of transfer directly to the character purchasing them, you would vastly improve the single player or low-player co-op experience! It's rough having to manually buy medkits and pills for each bot.

None the less, these are mild things that can be repaired. I wish you good luck!

- A good concept for a money system
- Another good concept for the slot machines
- A cool delivery method for your escape
- An overall fun concept

- Slot machines can be triggered by hitting them with gun fire. This results in bots wasting hundreds of dollars on items you don't want.
- While the upper tier fences state you "Get what you pay for" neither are better than the Chainlink Fence, which is the best deployable in the map bar none.
- Money comes way too quickly, so once you obtain T2 weapons including the Magnum, you can pretty much corner camp until you have money for the car.

I've been looking forward to trying this one since I read about work being done on it over the Source mailing list. It was a highly unique concept and I love the slot machine idea. However, there's some gameplay balancing that I think would vastly improve the map's core systems.

Namely, the Chainlink Fence should be moved to the top tier of walls, and the others knocked down. Second, gunfire should not trigger slot machines. If you have even one maniac bot with a shotgun, you'll be buying dozens of items you don't want. That hardly slows you down, however, as it seems corner camping as soon as the upstairs is walled off (a few walls can slow infected flow in the front yard, but are largely unneeded) is an extremely viable strategy. You can hit the slot machine whenever you want to try for more gear and pretty safely dominate the map from this position. It renders many of the coolest elements unnecessary.

Long story short, I think with some pricing changes and such this could be a great map! I encountered a few bugs that I'll drop a PM to the author about, but definitely nothing crippling and I know first hand how hard it is to qaush them on a project like this.

I'm looking forward to the next patch!

Finally, putting a brief break in the early horde here and there would give the bots a chance to heal - as it stands, they will outright refuse to through the first 5-6 minutes resulting in a bit of an artificial challenge.

- Isaac Clark finally gets a L4D model!
- First person arms add a lot
- Well animated without clipping issues many imports have

- No helmeted version yet
- Metal needs an updated specular; looks like leather
- Medkits unfortunately blot out the health bar area

I think if the metal parts of the suit can be given a more gruff, metal like reflective material (instead of the fully reflective/shared reflection with the non-metal parts of the suit), and the non-metal part gets less reflection, this will be a 100 for me; if I didn't know what they look like from Dead Space, I really would think he was wearing leather. In fact I'm going to pre-rate it at 100 and cross my fingers for a fix on that because this is great in every other way.

I've wanted an Isaac model for personal testing of my campaign since I'm lacking character models, and finally I have one!

- Extremely long campaign
- EXTREMELY tough campaign (this is a pro!)
- Amazingly well polished

- A small handful of very minor glitches
- As mentioned, the horde doesn't shut off during the finale tank. This is only really a problem if you're trying the campaign out solo, and can only carry one grenade at a time; I was able to escape by ditching the bots as decoys. I appreciate what you're going for here - I think it could be fixed simply by adding a few more bile / pipes in the area where the tank spawns, so you have a reasonable chance of getting one. This would also fix Versus, which would be outright impossible this way; another idea is to add two tanks (instead of one) and provide more physics cars. As it is, it's only really possible with a full grenade wielding team.
- The Church is a bit confusing, with no indicator how to open the door; the bots don't follow you to the exit until you go there yourself. It took me several minutes to figure out how to get out of it. Only part I got lost in, though! Great atmosphere - adding a Hint would fix this.
- As a minor bug, the ending was broken for me; it "killed" me while in the credits, and I saw 0 for most stats (such as kills)

I'm disappointed this isn't even higher rated. Frankly I think that some people do not like very rough campaigns, where ammo is very scarce and Tier 2s are extremely rare - something you need to go out of your way to find. They also might not like maps with lots of exploring. I'm the reverse on every count - I loved this map all the way through and the difficulty is what put it over I Hate Mountains for me; it's a rough map that punishes you (The message on the map 2 saferoom is hilarious) and makes victory rewarding. Hell, I had a rough time on Advanced with bots, though managed to not die until the last map from the tank / not realizing that the gauntlet path was random on my first go.

Also I really like how it makes heavy use of the Defibs, and has little to no closets - I never had an ally come back at a closet, but there were enough defibs that I was able to revive them all, with the exception of Coach falling off a cliff.

Highly recommended.

- Excellent map design
- Very, very long maps (this is definitely a pro)
- Good use of decals to indicate paths
- Plentiful L4D2 upgrades; not a straight L4D1 port
- Lots of side rooms and areas to explore, and alt. routes
- Good use of pre-existing dialogue
- Nice new music and SFX

- Minor framerate hiccups at a few spots; not enough to seriously impact my computer, but noticing the drop means a more mid-range system might have a problem
- The helicopter crash reason is a bit unexplained; no indicator of where it's landing if you didn't notice the helipad on the way in; I got incredibly lost the first time and ultimately had to pause and check youtube.
- Too many items make things abit too easy at times; almost every side room has a huge chance of containing pain pills, ammo, grenades or adrenaline. This stopped around map 4, but then resumed on map 5 with a finale area brimming with pipes and molotovs. This allowed me to breeze through the map on my first try (other than getting lost at the helicopter).. I'd say a 50% reduction in medical/throwables on maps 1-3 and 5 would be a huge help.

All of these are pretty much nitpicks and didn't detract from my opinion of the maps at all; the last issue might be a problem if you were planning to play it Versus, however. I'd recommend Expert Realism if you want to co-op it with your friends.

This campaign should have been selected as a Valve supported one over Cold Stream. Cold Stream isn't as bad as some people would make it out to be, but doesn't have anywhere near the polish or entertainment value that this does. This is pretty much the only current custom campaign that I'd say is nearly flawless and shows what can be done with L4D mapping. I'd say it's the gold standard.
