BioShock vs Standoff 2
BioShock
BioShock is one of the most highly acclaimed steampunk-themed shooters that has a very interesting twist - your very character's DNA can be modified through the use of a selection of plasmids and a special resource called ADAM, allowing you to have superhuman abilities which will serve you well, sometimes more so than the weapon you wield, in your adventure through the fallen underwater city of Rapture. Aside from the many violent mad men (a.k.a. Splicers), the game also provides players with challeging encounters with the iconic Big Daddies and Little Sisters.When it comes to non-military-styled shooters with an intensely immersive storyline, BioShock is among the handful of the "best of the best" (which includes the Fallout series, the Borderlands series, the Deus Ex series and others). The game boasts of having a rather dark storyline that actually challenges you to think about it in a more in-depth way; to link all the clues together to get the complete narrative that is surprisingly a lot more engaging that you'd expect.
2K Games has just released the remastered version of the very first Bioshock last year and if you can get it on Steam, you really should. The very unique experience it can offer you is very well worth the cost.
Standoff 2
Standoff 2 is an intense yet entertaining MMOFPS game where you get to either play for the terrorists or the special forces in a team-based shootout. The game features several maps as well as 3 exciting and competitive game modes, namely "Deathmatch", "Defuse the bomb", "Arms race" and "Tournaments". As you might expect, the game also offers a ton of fancy and cool skins for your weapons and a way for you to trade them with other players. The game even has an in-depth social system that allows players to message each other, use both text and voice chat to communicate while in-game, and add other players as friends.If you have always enjoyed playing Counter-Strike or games like it, Standoff 2 is basically a really well-polished version of that exact same game which you can play on your mobile devices while you're on the go.
