Argo vs Last Man Standing
Argo
Argo is hardcore tactical MMOFPS that is, according its developers, a free total conversion of the popular Arma game franchise, specifically Arma 3. Although the franchise itself as not reached mainstream popularity like Counter-Strike, Battlefield, and Call of Duty, it has a niche and dedicated fanbase that you'll probably see a lot of while playing this game.Featuring a three competitive game modes and one 10-vs-AI cooperative mode, the game is set in the Mediterranean island of Malden that houses a range of combat zones perfectly designed to fit each mode. The game even has a built-in 3D scenario editor that allows you to create your own missions and other content for Argo players to enjoy!
If you love military-themed shooters, Argo is a pretty solid game to play. After all, you'll get to experience a bit of the famous "Arma gameplay" for free.
Last Man Standing
Last Man Standing is a battle royale game that is similar to PlayerUnknown's Battlegrounds (PUBG) in many ways, including graphically and gameplay-wise, but you often have to remind yourself that being a free-to-play version, this game does have its own set of flaws. For starters, although the map in this game is as vast as PUBG's, there are no vehicles in Last Man Standing, forcing you to travel large distances on foot. There isn't any bullet tracers or obvious muzzle flashes in this game either so it can be quite difficult for you to pin-point from where you are being shot at.Some players also report having frame rate drops which may indicate poor game optimization and well, since there isn't any anti-cheat in the game, you will have to content with having some cheaters in the game (still less than 50% of the time though). Matchmaking takes quite some time as well since the player base in this game is obviously a lot less than PUBG or even Fortnite Battle Royale.
That said, the game has some redeeming qualities aside from being free-to-play, such as having a fun and sometimes intense and competitive gameplay; insanely in-depth character customizations where you can earn more outfits and clothes by playing; a nice arsenal of weapons that you can find and use, including the very useful riot shield-like barriers; multiple game modes (solo, duo and team-based), and more.
So, Last Man Standing is a pretty decent alternative - the free-to-play sort - if you're looking to play a game that's more similar to PlayerUnknown's Battlegrounds rather than the more cartoonish-looking Fortnite Battle Royale. Granted that this game isn't at all perfect and that apparently the devs won't be patching this game up anytime soon, this is the best you'll probably get!
