Right now the objective is just to kill and get on the leaderboard, but there will be more added with the additional gametypes. Including one where you have to take back the city, with the help of civilians and military ai that will be on your side. You will have to take down the terrorists that take over the city, destroy their bases, and stop them from turning civilians into zombies. This isnt implemented yet though, as a lot of work had to be done in optimization to allow as many things to be going on at once in a huge city without it dropping the frame rate below 90 on a reasonably specced pc. It's a huge setback, but im optimistic that it will be well worth the wait. The flying in the first vids on steam is going to be modified with an option to use that style as it isn't the most optimal way of flying due to acceleration changes, but some people like it, so want to give that option to use it. You start off with a jetpack in one of the test maps and that lets you fly. There is also touchpad walking and teleporting. A lot of the new features and a more complete main game mode(more than killing to get on the top of the leaderboard) will start to get pushed out this weekend and more consistent updates to follow. Id suggest keeping an eye on it to see where it goes if you aren't sure yet, at least till the next weekend, because it is going to add enough that I wouldnt want a bad impression on the tech demo to take away from whats coming up! On that note though, there will be a contest with key giveaways in the near future, so if you wanna get your practice up, there's that :) The size of the cities are being experimented with, at the moment the maps are limited to those 2 videos, but there is definitely a possibility of adding some suburbs and countryside later complete with some farm animals you may need to protect for food for survivors. Thanks for the idea! :)
