After another try, I beat this campaign. Actually this campaign is worth 4 maps, because map 2 is long enough, including the rush event to the saferoom on the great wall of China. On map 3, there are hard way & easy way to melt the ice blocks. The hard way is by throwing the fireworkcrate & estimate how long until the fireworkcrate slide into the circled highlight on the ice & then shooting it (because the ice melting event can only be triggered when the fireworkcrate is right inside the circle). If you miss the spot even an inch, the fireworkcrate's spark won't damage the ice block at all & you have to pick another one. Then, the easy way but with longer time is, carry the fireworkcrate inside the circle, then, instead of throwing it by clicking the left mouse, just press "Q" to swap weapon, & taraa, the fireworkcrate just drops without sliding. Move far enough from that spot then shot the fireworkcrate (this method works 100%). . & then, here is the overall review: Pros= - The supplies are enough. - Nice Chinese instrumentals during transition & credits - No bot navigation error - No texture error - The hints & highlights are clear, including the highlights on the fireworkcrates on finale. - Map 2 & 3 are explorable. . Cons= - Map 1 is rather short because the mission is just to collect the parachute bags. - Map 2 is rather long due to the explorable wide area & the route for rush event near the end of map 2 is rather long while at the same time zombies & SI keep spawning so that makes the rush event more difficult (but challenging though). - On finale, the ice ground is slippery so that makes the survivors have hard time to move during panic event or event a battle with a tank. What makes it illogical is the zombies just run as if they're wearing ice skates! How come they don't even slip on the ice?! :o . Actually it's kind of funny & gives more entertainment if the zombies also slip on the ice. Imagine how a tank pursues a survivor & suddenly he has to turn right following the pursued survivor but he slips for awhile :D . - Due to the ice's slippery effect, throwing fireworkcrate to the circled highlight on the ice block is more difficult because the fireworkcrate also slides. Even though there are many fireworkcrates, they can run out & players have to restart the map if they run out of fireworkcrate. - The ice block melting process needs fireworkcrate to be above the circled highlight before the exploding effect is able to melt the ice, & that increases the difficulty. I already gave some tips about this on previous paragraph. - If survivors waste too much time in collecting the fireworkcrates & melt the ice, the "cursed panic event" will be triggered where zombies + a tank will keep coming & each time they kill a tank, another tank will come in seconds, & this will make the map impossible to finish as the ammo will run out really fast during the "cursed panic event". So, melt the ice quickly if you don't want to trigger this "cursed panic event". . In overalls, though it's kind of short to explore only 3 maps, it's a nice campaign :) . By the way, for personal use after finishing the campaign in normal way, I changed the "damage filter" function from "filter_invincible" to "filter_burn" & as expected, the ice blocks could melt as long as the firework sparks hit the circled highlights. Even it didn't require the fireworkcrate to explode inside the circled highlights. I'll use the modified version to play with friends, to reduce their frustration in walking on the slippery ice while being chased by zombies & tank.

While it at first seems it is a short three-map campaign, in reality it would take much longer to complete due to a number of factors. The first map requires you to find four randomly placed parachutes (some of which may be somewhat well hidden). The second map has some randomly blocked paths, somewhat increasing replayability and dragging you for more Great Wall runs. And that Gauntlet, oh my. The finale has a frictionless ice you need to melt, all the while being attacked by hordes and Tanks. And gods save you if you take too long. The atmosphere of the cold, deserted Great Wall is great, however, even though I generally like more lit maps.

So there are some really cool ideas here that work: the airplane in flight, skydiving to escape, the great wall and the ice breaking finale. The mechanics are all there, and the campaign is a lot of fun. Those are the most important parts, and they are very well done here. What can be improved: - the parachute packs are small and hard to find (maybe because they are small) - the lighting can be made more dramatic and exciting, and still be realistic - the paths for level 2 are a bit confusing on the wall. A bit of better directions (markers) can improve things here. So overall, I think this is worth keeping, replaying and enjoying. Well done.
