Visually, probably the best mod for Deus Ex, with interesting and atmospheric locations. The mod is let down by poor performance and the writing, which is reminiscent of Redsun2020 and shares the same flaws.
The end mission and boss fight were definitely the low point; the boss is damn near impossible to beat without exploiting the engine AI. He disables grenades mid-flight and wipes out your bioelectric reserve if he gets close, meaning you have to try and shoot him from a distance while dodging his shots (which will instantly kill you.) Boss fights have always been terrible in Deus Ex games, but this is by far the worst I've ever seen.
The endings were also very stale, which was a shame given the interesting cinematics earlier in the mod.
