I took a try of this game. During the first game I wasnt able to move anywhere, although for a small moment I think it moved. I might have just got myself stuck behing that cover wall, since I noticed I got bit stuck there later too.
Second game I got much more into the game already, but even in first game when I was stuck, I instantly liked how the slow shooting felt, and how I first thought it was gangsters vs cops, those cars being police cars, but actually it was just too teams. But point here being, Felt excited at beginning when I thought it was like that, hence, a story game with a level something like this could be a lot of fun.
Basically I spent much more time playing this game than it should really take to play a game this unfinished, by other words, although game is clearly lacking and there isnt much to do etc. the core is prettu fun and kept me playing longer than I would have thought, although still only a short while, but several games, maybe 5 in total.
I also very much liked how some of those defensive walls had those machine guns, unfortunately no sound there yet, plus from the two that I found, only one was actually shootable, since the other kept shooting against the wall. But darn I enjoyed using that machine gun to shoot around.
I also liked the two teams, as in, I wasnt alone there, but there were others, and with this simplistic up view.
And also liked how the cars were destroyable too, that too added to the games funness a lot, even the slow decay of the card towards the destruction was still missing.
I can easily see this could turn into a real fun game. Make some story, or make it some sort of conguer big qorld map and each terrain has a fight, and make different levels have variety and this can be lot of fun. Like some levels you go alone, some with couple, and some with similarly massive amount of peeps on both sides.
It looked good enough etc. that I wouldnt concentrate on polishing things anymore that much at this point, you even had night-day cycle there etc. now you just need to concentrate on building a story, by which I also mean building the levels.
Basically even playability is mostly there already, just avoid getting stuck on those defensive walls etc. and you are mainly in need of building the world around this game.
