Argo vs Battle Carnival
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.
Battle Carnival
Battle Carnival is a unique MMO shooter game that attempts to combine the strategy that goes into character-switching in character-based shooters like Overwatch with the somewhat arcade-like gameplay that the fans of the age-old yet iconic franchise, Counter Strike, might be very familiar with. Featuring 7 early access characters that you can access right from the start, the game puts a lot of emphasis on the roles these characters can play and how by switching some of them up, your team may be able to counter the enemy's lineup. Of course, knowing how to aim is still a crucial skill needed in any MMO shooter.The game provides 2 game modes at the moment - Demolition and Domination. Demolition is the clear favorite since the 5-vs-5 matches there are usually pretty fast-paced - 3 mins per round and the game can be won simply by winning 5 rounds. Domination, however, is slower-paced and features the "capture and hold the area" gameplay. It's a 6-vs-6 match that can last up to 12 minutes or so. The maps are all very well-designed with multiple flanking and outflanking routes, though some may complain that the maps are confusing and "maze-like".
Battle Carnival is currently in early access and as such, the game does have plenty of problems that need to be fixed, areas that need improving and of course, more features and content that need to be released. The player population is a bit on the low end as well. Regardless, the game does seem to have a potential to fill a niche that buy-to-play shooters have hogged and with changes, it can be better. In the meantime though, you might still want to give the game a try, just so you can let the developers know about your feedback and help them turn the game into a game you'd want to stick around in.
