If you're a fan of the Sniper franchise, you may want to look into picking up the Sniper 3 Ultimate Edition. The extended collector's edition of the game will include various extra digital features that are not available with the base game.
Unfortunately, there will not be any additional physical content for the Ultimate Edition of Sniper 3, so in a sense, purchasing the Ultimate Edition serves as buying the season pass for the game.
Inside of the Ultimate Edition, players will receive a 3 part 'Save Churchill' DLC. On top of the DLC, six different weapons packs will be included. The weapons packs available in the Sniper 3 Ultimate Edition have been listed below.
Hunter Weapons Pack
Camouflage Weapons Pack
Patriot Weapons Pack
Sniper Rifles Weapons Pack
Axis Weapons Pack
Eastern Front Weapons Pack
Additionally to the above content, the Ultimate pack will allow players to access a few new multiplayer modes, including The Shooting Range for single player, the Twilight Strike Overwatch Mission for co-op play, and Capture the Flag for multiplayer.
Finally, the Ultimate Edition will receive new multiplayer maps, all six of which have been listed.
I find it a little odd that some of this content hasn't been included in the base game, and whilst it's nice to have an easy-access package to all of the Sniper 3 DLC, it's a shame that modes like capture the flag or the Twilight Strike Overwatch mission aren't already available for free.
