Ahhh, a good, rather easy FPS to play, with great mutliplayer and map editor.
The gameplay is great, with some innovative elements added in for addictive gameplay, easy, but still addictive. The graphics are excellent, the greenery and the water look very good. However, the main selling point for me was the game's map editor. Though limited in some aspects, the map edtior allows for great multiplayer maps for intense battle with your friends.
This game is a sure buy, I would recommend it to any FPS fan, and it has online multiplayer. So Far Cry: Instincts is a good buy.
