A pretty solid single player experience as a near-future, open-world, Military themed FPS. The open-world mechanic is refreshing for a single player experience (that isn't battlefield with bots) compared to the modern military shooter campaigns which are very linear. There's still a hint of linearity as each mission is basically about 3 target objectives (at a time) you have to capture/destroy but you can pretty much get to each of them in whatever order you want. Then another 3, and so on, until you've basically hit ever point of interest in the large scale level. It plays out somewhat like Crysis (1) or FarCry (1), but better in my opinion because the combat comes sooner, is more sustained (more ammo, more bad guys, & less time traversing the map), you have allies to fight alongside you, you're given more choice via multiple simultaneous objectives, and the level design is more than just a jungle (it's an urban jungle)
This game lets you use vehicles (tanks) but you can survive w/o having to use them (unlike fights in battlefield). Then there's also using drones (RC cars/helicopters with mounted guns/bombs), which occures quite often-more than I would wish in an FPS game but at least its not the majority (or even the entirety) of any particular mission and It's possible to get the through the mission w/o using them, though can be difficult at times.
Graphics may be slightly dated, but they're unified and solid. Sound is generic but it gets the job done well enough without detracting too much from immersion. Dialog is simple, not much depth. Same with the plot, but this is good as it doesn't try to cram a bunch of narrative/history into your brain when you've come to play a shoot 'em up action game. The controls are tight. You have health regeneration so as long as you have cover, you can almost always stay alive. There are still times where you may die, but the open-world game mechanic makes dying less frustrating as you are not forced to follow the exact same path that just got you killed!!
Overall, great fun playing the single player campaign as an open world shooter. I was disappointed with the last few levels in the cities as you couldn't enter many of the large buildings which greatly restricts your movement and attack options compared to the previous levels in the game.
