I recommend reverting CS back to the older engine, but adding in the Office Map.
Speaking of Maps, I recommend adding a few.
Number one is Dust 2 from CSGO, you can find it easily, you can even find one suited for your engine, it can be found in Special Strike, If it does not fit, maybe just make the textures a bit more basic. Because that map is awesome!
Another Map that would be great is City from War Attack
another game that has minecraft like graphics, it is very wide open, and I love the parcour.
Also, for the Cartoon Strike App, it would be nice if running was automatic like in Special Strike Mobile and Unity FPS Kit 3.0.
And also an aim helper, and cross platform. That might not be in the Fps Kit, but you seem to know your way around it control wise, so I don't think that is too hard.
Also, dying gives you $400, which has been taken advantage of by one of my friends and has made the game less fun.
And on the Farm map, you can easily get out of bounds and makes it really easy to get the sniper.
Finally, Flash Grenades would be great and so would Bomb Defusal.
I hope you will add at least some of these, and at least fix the newest update! CS is one of my favorite FPS games and I don't want to have to stop playing it!
