Challenge mode is so annoying, forced to do almost exactly the same design over and over with a slight adjustment over 10times, there needs to be a less annoying way.
It's not a bad game but you REALLY need to fix the AI in this, when I want to kill my team more than the enemy because they're just cannon fodder you know something is wrong with your game design. Secondly why would you design it so in order to get good weapons you MUST replay levels? That just seems like bad game design to me.
Seems like a rushed, unfinished game. Beta at best. The game is riddled with bugs and annoyances like guns that miss every second shot making them not worth it compared to melee which even then I didn't see any point to the melee skill because damage was always what was on the weapon and it basically never missed anway.
The game itself is pretty boring, go through area, search, kill zombies, search etc. The side quests are nothing special and teh weapons are all pretty lackluster. I've come to expect better from conartist and I must admit I'm thoroughly disappointed, in the future I hope you bugtest and perfect a game before releasing it, instead of putting out an unfished pile of crap.
For level 8, go OVER the pillar, not underneath like in the ace video, that's pretty much impossible.
Skip level 6,I tried what was done in the ace video many times and couldn't do it, level 11 is much, much easier than level 6.
There needs to be a way to accurately change the speed, like a slider otherwise it becomes too difficult to find that "sweet spot" and instead you bounce around it.
Invest heavily in headshots/small weapons and buy the sniper rifle, it's better than pretty much all other weapons when you're doing 1000+ damage plus a shot.
It's kind of annoying that the difficulty in this game doesn't game from gameplay elements or level design but because the controls are so sticky and convoluted not to mention you don't even have to be touching hazards but be within a certain area and die.
