I cannot recommend the game at its curent state.
Have been playing this game for a little over six years now and accumulated 2600+ hours in game.
Still wish Operation First Light would be in the game...

The "recent" Infantry Combat Overhaul really - REALLY - destroyed the game for me.
It favours bush wookies instead of aggresive infantry gameplay. It's not tactical, it's just lame.
It's a game at the end of the day and it should be fun. Squad is NOT milsim like Arma and it shouldn't try to be.
It's infuriating sprinting for 10 seconds and having to wait another 10 until your character's noodle arms stop swinging like a freaking car dealership air dancer. Eventually you take the shot but even if it's a headshot there's a 50% the enemy will survive.

Also removing the dead-dead status some years ago was a bad decision imo. It just encourages players to run around like headless chickens without fearing for punishment for doing so. Now THAT was much better at slowing down the game's pace without that noodle arm bullcrap.

Now whoever's been playing this game know optimization is just terrible. It still feels like an early access game, although it's being developed for almost 10 years now.
Game also doesn't look great. Some maps have been revamped (aka added some bushes and trees) and are kinda ok, but after a while they tend to get repetitive.

There are a couple good things about the "game":
1. Its community. There are several clans that have been around for ages now and without them populating the servers the game would've been dead by now.
2. The mods created by said community. Some mods allow you to play with the "old" infantry mechanics so you can actually have fun. Through what were originally mods, new factions, vehicles, guns have been added to the game. Don't think OWI would've ever come that far without these mods.

This game is only still around because there is no competition at the moment.
I hope that changes soon, same as happened to Tarkov with Gray Zone and Arena Breakout.

Infantry Combat Overhaul making it so your character can't keep a rifle steady on a man-sized target at 25m is asinine. I understand wanting to make the game slower but having a wacky wavy inflatable arm tube man as a trained soldier is absolutely ridiculous.

This game used to be amazing. And largely, it still is. But the recoil and suppression changes are horrible for those who have played the game for years. When I cannot shoot someone three feet in front of me, that's an issue. When my ACOG takes thirty seconds to stabilize, that's an issue. When small arms fire over my head makes it seem like I am convulsing to no end, that's an issue.

Vehicle gameplay is awesome. In my opinion, it's the best around. Rolling around in a BTR or Bradley fighting among infantry is surreal.

But the weapon play is god awful. I wish they would change it back to the old Squad, or at least rework what they've done.
