When I started to play this, suddenly this reminded me of both No Mercy & Dead Air. Some environments looked like they were brought from those official campaigns. However, that's no problem to me as I could enjoy the play to the end with no error on bot navigation & no crash. . Pros: - The campaign works well - Bot navigation is fine - Supplies are ok in both medkits & weapons - The hints & highlights are clear . Cons: - All maps except map 1 & finale have endless panic event + SI. - Map 1 is too short. After the alarm door, survivors just need to walk for few seconds to reach the saferoom. - Tank on the finale often gets stuck & commits suicide. From 2 Tank events, only Tank from 2nd event came to chase us. - The location of rescue helicopter is predictable. - This campaign is like the lite version of No Mercy & Dead Air mix . In overalls, the main problems of this problem are only two: endless panic event & tank getting stuck on finale. But I'll keep this campaign to play later because the bots & maps work well :) .

This has to be the weakest campaign I played in a while. It is very dark at all times, up to the point it is teeth-grindingly and eye-hurtingly annoying. The maps have almost nothing original to offer (they may even be well-built but you can't tell that in the eternal darkness) and flood the gameplay with hordes instead. The first Tank in the finale had an aneurism, but he had his revenge when two of them appeared later.

There are a few visual issues with this map - an elevator top that disappears into the shaft ceiling at the start of the campaign, oddly thin walls and floors, and the curse of most custom campaigns: a grid layout with every path, angle and piece of architecture comprised of 90 degree angles. There are even a few sections that seem to be lifted straight out of No Mercy. Another issue - the campaign seems like a series of alarm events, one after another - maybe trying to ramp up the difficulty. The low point is the train event - not an interesting or fun place to defend. The high mark - ascending through the construction area over conveniently stacked sacks of concrete and wood. The lighting and atmosphere, however, are pretty solid. But the campaign offers nothing new or interesting - compared to the stock maps, it is bad. Compared to most custom campaigns, it is slightly above average. Not near the cleverness or polish of the really great ones, but above the really amateur ones that clutter most of the file storage space. It is not a keeper for me, but it wasn't a complete bore for a one-time excursion.

Pros: - Hordes and SI spawn absolutely normally; - Decent weapons and supply all over the map; -Infinite horde, I love infinite hordes that doesn't spawn within us; - Big maps; -2 ways to follow through in map 2; Cons: -Some alarms still ringing and the horde stops; -You could have sorted the models a little. It feels like we are playing a mashup of No Mercy and Dead Air, but although it isn't so original its a good piece of work; -Sometimes a tank dies alone in the last chapter; Conclusion: This is certainly one of the 100 top maps. Congratulations for make a nice job
