Very fun. Only reason people are giving this game a bad review is because they suck at first and dont give it a chance.
Shootout is like a History's Channel Mod for the Half-Life series. You play through some of history's most famous battles, what i like about this is that the weapons, scenary and the character models are fitted perfectly for the level. This brings a lot of variety in every level because there are different weapons and characters
A bad thing is that Shootout isn't making anymore maps for the game. So we'll just have to stick with the like 14 we already have. If you don't like the game, you can just uninstall it, Its free by the way. :D
