Welcome to Cabela's Dangerous hunts 2013,
First there is no real co-op online as stated. Only local split screen.
During your short stay in Africa you will kill thousands and thousands of lions and wild cats because of their infinite spawns. You will regulary get scratched by wild life with little to no effect.
You will have to slide long slopes because every cliff edge will crumple under your feets. The local wild life will use cheap scare tactics like jumping in and out of your view every 5 minutes or so.
There are mandatory "flash back" every 2 or 3 levels to change the theme from Africa to northern America for snow effects and to change to wolfes. Animals seems to come in waves of 4-5 and are not scared of your gun even if you just murdered to whole pack before their eyes. You will also have to save your brother life by sniping several dozens or so of animals trying to eat him whenever you are apart.
You will also get numerous "bullet time" with X-Ray vision to snipe the heart or brain of the predators and the only way to avoid attacks usually consist to roll left or right when they leap. Whenever the sneak up behind you, you enter a slow-mo shoot their heart quick mode.
Numerous bugs will also be encountered like animal going through wall or jumping off cliffs.
Several uninterresting other modes are included.
