[The developers use real-life military weapons, equipment and vehicles](https://forums.bistudio.com/topic/125727-is-arma-3-authentic/). Even some of the environments in the game are virtually indistinguishable from their real-life counterpart. ARMA 3's gameplay also encompasses more than a regular first person shooter, as military tactics such as water attacks, giving orders to squadmates and drone strikes are necessary in order to successfully complete a mission. Elements such as destruction are extremely important, as certain specific parts of a vehicle can be damaged.

Pros
Pro Works well on most hardware
This is not very a resource intensive game, meaning it should work just fine on lower end systems.
Pro Fantastic community
Great community will keep you coming back for more.
Pro Very good graphics
The game has pleasant and realistic graphics that should appeal to anyone looking for a real life army shooter.
Pro Easy to try
The game is free, meaning there is no cost to test the game in order to see how it performs or if the gameplay is appealing.
Pro Competitive at highest levels
Someone who's not good at this game won't be able to kill someone who knows how to play by luck.
It could happen ONCE with an across-the-map grenade but it is not like Call of Duty multiplayer where you end up killing someone eventually.
If you suck at this game or if these are your first match don't be surprised to have a 0-15 as K/D at the end of the match.
Pro Best in class authenticity
ARMA 3 is built as a simulation-type game and features rather tactical gameplay with a slow pace. The developers use real-life military weapons, equipment and vehicles. Even some of the environments in the game are virtually indistinguishable from their real-life counterpart. ARMA 3's gameplay also encompasses more than a regular first person shooter, as military tactics such as water attacks, giving orders to squadmates and drone strikes are necessary in order to successfully complete a mission. Elements such as destruction are extremely important, as certain specific parts of a vehicle can be damaged.
Pro Huge open maps
As ARMA 3 is an open-world experience, singleplayer missions are not as linear and take place in the same map area as the game's multiplayer mode. There are a couple of different islands to explore in ARMA 3, including Altis which has a size of over 100 square miles (270 km²). Stratis is the smallest island in ARMA but is still respectable in size but 7.7 square miles (20 km²). A new map - Tanoa - is scheduled to be included in the paid Apex Expansion pack, with a size of 38.6 square miles (100 km²).
Pro Huge amount of mods and add-ons available
The modding community of ARMA 3 is quite large, with multiple online communities and free tools provided by Bohemia - the developers of ARMA 3. At the time of writing, there are 115 mods available on ModDB and over 23500 mods in the Steam Workshop.
Pro Steam workshop
So much content on the Steam workshop. You can get 200 GBs of mods in 2 days.
Pro No player limit in multiplayer games
ARMA 3 doesn't impose restrictions on its servers, allowing for a true sandbox experience with a large population. Battles can be fought with hundreds or even thousands of players; multiplayer warfare is definitely large-scale.
Pro Long single-player campaign
The average playtime for the single-player campaign (referred to as 'Main Story) of ARMA 3 clocks in at just under 20 hours, while a 100% complete playthough of the campaign averages 39 hours of playtime.
Pro Underwater gameplay
ARMA 3 features underwater gameplay with diving gear and underwater weapons. Underwater gameplay is noticeably different, because it uses a third movement axis.
Cons
Con Uses Steam
Con Controls are unique and can be a barrier
It's not as simple as ctrl for crouch. While many tactical shooters use a similar s=control scheme, ARMA takes a sharp departure from the norm. This is part of what enables it to have far more robust/tactical movement.
Con Steep learning curve
The tactical aspect of ARMA 3 is also portrayed in the somewhat difficult controls and steep learning curve of the game. For example, a lot of different buttons and keystrokes have to be remembered for all the different commands, equipment options and vehicle controls. There is no in-game tutorial, the only way to learn how the game works in by trial and error, a field guide or by using in-game hints. Tactical elements and strategies aren't explained in the game.
Con Framerate isn't consistent
ARMA suffers from some framerate issues, with very variable results in both single- and multiplayer situations. Often the game will perform well in multiplayer, while dropping down to a severely worse framerate in a single player mission. Similar problems occur vice versa as well, which results in a very inconsistent framerate.
