A classic remade. Literally. But it's not perfect
The Deletes Scenes part is also o.k. for me. It could've been better, but they mapped and did single player missions for a game I love, so this counts aswell. Also, the weapons used are all from Counter-Strike so even better.
The multyplayer and singleplayer in the normal Czero are good. MP goes great, some itens from classic cs plus that Galil, shield and french rifle. The missions you find in single player can make take some time, but it depends on skill, so other than that, it can kill some time, but it's definitely not the best thing to do.
Go for it, if you want a good game, cheap. Not the very best, but it will serve you well enough.
