Finished it. Overall I enjoyed it, except some parts.
When the demo came out more than two years ago, I really liked it, and I couldn't wait to play it, but they devs delayed it until August of the last year, that turned me down.
I got it at the summer sales, played it, but didn't liked it, just played thirty minutes and quit, and I wanted to prioritize other games. I gave it another chance in May of this year, didn't like either and quit it again. One last chance this month, and finally hooked me. I couldn't stop playing it, the first maps are great.
It's a good game, not as good as Duke3D or Blood, but I found it more compelling than Shadow Warrior at least. (Which I never found the way around, beyond the original setting, the artistic design and Lo Wang, whose awesome, and in my opinion way better than Duke or Caleb, at least their one liners are fresh and more original, and not just stolen from movies)
It's entertaining as an FPS made on the Build Engine, but it lacks that spark of creativity and freshness that the classics had. In that sense, the setting and the design of the enemies feel uninspired, but even so, I wouldn't say it's bad, could be better for sure, but they have their thing.
The weapons, while it is the same as I said before, nothing special except the Bowling Bombs and the dart, at least they are fun to use and satisfying. In Shadow Warrior I never liked the weapons despite their extravagant and original design, I always felt them weak or ineffective, it is the only thing that I never closed off from that one.
I liked most of the maps, most of them are really well done. The exceptions are the fifth zone, with that forest and the sewers, so boring. And parts of the last zone didn't seem interesting at all to me.
What surpassed me is that beyond not being original in the creative part, that they have to included those shitty zombies. Really?. Were they necessary?. What a joke.
The bosses, some are challenging, but all forgettable, and the ending is not the exception, frustrating the amount of hitscans enemies everywhere around the map.
As for Shelly Bombshell Harrison, sorry, but she is pretty lame as a classic FPS character compared to the classics. Although she steals phrases from movies here and there, she is simply boring as a character, to be forgotten.
Conclusion: it's ok, I enjoyed it despite some of the flaws, and for these times, it seems to me that it is worth playing it at least once. I doubt I'll play it again anytime soon thought.
