Nice original campaign
Great design
Clever idea for making Molotovs

Could've been more medkits in the 2nd part (soldiers made it a bit tough)
That tank in the sewers. It's too slow to walk in there so it wasn't the best idea
I never found a use for the Fireworks

I enjoyed most of it apart from some of the tank spawn locations and the soldiers were a bit annoying, although a nice idea. I liked the corpse-looting near the end of the 2nd part. It's a shame you only used it once, or once that I know of. I thought the item-escort (ie: Cola and Fireworks) was a bit annoying and didn't really seem worth it. With the Cola bottles, I would've thought you'd get 4 Molotovs out of it since it was the standard 4-pack you carried. Still, I enjoyed the campaign and while the chinese theme was minimal in the map, it made sense since you were going through cities. Nice work.

Accurate representation
The healing stew was a nice touch
The messages on the floor

Finale was a bit of a let-down

I see a lot of people saying that the map is quite short. I think it's a fair size, but that's because I don't know the maps too well. For the few maps you used, you chose some decent big levels to get lost in. As for the finale, my preference would be the arena where you fight the machine-gun guard. There could've been consecutive tanks fought in there and when you escaped it would've been fun to somehow have that classic jump-in-the-air "yeaahhhh!" at the end. Good job though. You should do another of these perhaps with some Spear Of Destiny levels.

Well-adapted for L4D-style play
Beatable with bots

Just a personal preference: I would've liked the inclusion of the spinning blades and gas fire.

Really nice job on the conversion to L4D2. The maps may not be your's, but it's what you do with them that counts. The rush on the train tracks was a nice touch and felt similar to HL2's gameplay. The finale was well-executed with a well-placed mounted gun. I enjoyed this and I come back to it every now and then. An iconic map!

Interesting idea
Good detail with lots of vantage points
Air Support was a nice touch

Multiple of the same Special Infected come in at once

I made several attempts at this and managed a Bronze medal a few times. The only problem is that some of the special infected come in two or three at a time and can easily incap all survivors at once. Tanks seem to spawn very quickly aswell, though thankfully not as rapidly as the other special infected. Perhaps tone down the horde a bit, that's my only complaint. The strength of the horde would be better suited on a bigger map.

Great tribute to Super Mario Bros.
Fun Mario-related easter eggs
Most of the maps even the bots can handle

I thought Map 2 was a bit too dark in places
Map 3 is very hard to get through with special infected
Bots tend to die on the treetop jumps
Less frequent, but still a problem, bots can die from the Castle entrance's platform/fire traps.

Apart from the third map, I found this to be a very enjoyable campaign. Various flaws were presented in the aforementioned map such as the bots and special infected (specifically Chargers and Jockeys) making it harder to progress through. To elaborate on the Castle entrance traps, bots die either waiting too long to jump and get hurt by fire, or miss the landing (thank god for the rescue room up ahead!). This would've gotten maybe a 95 except the third map's flaws brought the score down. Excellent effort though. I hope to see more maps from you in future. :)

Good design & detail
Helpful item placement
A good challenge

There could be more Pipe Bombs

Great job, really enjoyed this. An entertaining map. Not too hard, but not too easy either, so it has a good balance. I played through several times and my survival time was quite different on each attempt.

Nice idea
Resembles Zelda's dungeon gameplay
Plenty of Rescue Rooms in 2nd Dungeon

Not many Rescue Rooms in 1st Dungeon
Not recommended for Single Player
Sliding Blades can be a problem

This is one of those maps that's hindered with bots, so it's best for human teams to work together. The sliders are hard to avoid getting hurt by since you have to stand in their path to make them move instead of just infront of the path like in the games. I encountered some weird errors when I played last night in which the bots would stop moving at one point unless you left them far beind and they re-spawned near you. Great effort though.
