Still being gathered 🙂 I had a quick go yesterday.
It's a massive improvement on Arma 3 in many aspects but I'm a little worried it will be watered down due to it also being released on console. There has always been a very strong, almost symbiotic, relationship between BI and the modding community. Its the mods that make Arma what it is, it spawned the whole Battle Royale genre via one of its mods...and console worries me a little on that front.
But yeah: looks better, sounds better, plays better, driving is much much better...its still Bohemia Interactive and so has a few bugs... and what's available in terms of game modes is limited, at least for now.
It's not really a purchase for non Arma fans but worth a punt if you find it interesting.
