Spent around 10 hours in this game. Honestly I liked it for the first few hours...after that (I won't say I don't like it anymore) the enthusiasm dropped. The main reasons behind it are, the game is not well designed keeping single player in mind I think.I am playing in normal and it feels a bit easy, though I would admit I failed on some missions but thats due to the fact that I rushed. I rushed because almost every mission needs you to do the same thing.
Get near the compound mark enemies and move. However I found a easy way, if you do a drive by shooting then it becomes much easier your crew members will almost take out everyone in that compound & will make the game more easy. It may not work on every mission but it will work on almost every mission. I have no idea how it is on higher difficulty as I have not played on that mode but if you are playing it in co-op then you may enjoy it more.
The map is huge and there are many things to do but those many things are mostly repetition of the same things on different locations
. The game looks pretty I won't say it looks amazing but its looks good enough (Ubisoft might have downgraded it). The driving is also not that satisfying..when compared to GTA. Btw you have many vehicles in this game from boats to planes.
The 4v4 PVP multiplayer mode is good but cant say much on that as I have only played 1 match.
This is not my final verdict as I haven't completed the game yet.
