After 20 hours, I can say that Unit starts to grow on you. Well probably before that point. I often found myself thinking, "okay, this is the last round and then I'm turning it off." When I do finally turn it off, I realize I had thought that an hour before. This game is still in beta and I did experience some technical issues while I was playing.
As I mentioned before, the sound has some hissing/skipping/something weird going on. There isn't much you can do with the sound settings so I wasn't really able to play with them a whole lot. Also a few times a game has counted down to start and then instead of loading, it pops up a message saying "Please try again later". I immediately push join and it counts down again and joins the game which has already started. Also, I once played a round where we played for about 30 seconds it suddenly said "Game over, you win!" but there were no stats like we'd normally see and we were kicked back to the room. Everyone seemed very confused. Other than that there were no other clear cut technical issues.
There was an issue I found with a couple players. I don't think it was technical, I'm sure they were hacking. If you watch this video you can see towards the middle.
The guy takes a full clip to the face which bends him over backwards and he keeps running then shoots me through a wall from 40 feet off with a shot gun. He was doing that for a couple games. When I finally got host, I banned him. Screen name was "Ryuk" and belong to a clan who call themselves only "A". That was a couple days ago. Today I encountered him again with a clan buddy. They both seemed capable of taking far more damage than anyone else on the map. They still died, but slowly.
This map you see in this video is a Mercenary Free For All. These maps are fun for a few minutes, especially if you get a defensible position. However, they quickly turn into an episode of loony tunes. People can spawn almost anywhere and get a 3 second invulnerability when they do. You constantly have this situation where one person dies, someone spawns and kills his killer and someone else shows up and wastes him and then someone else spawns, and it goes on and on. A killing chain. It's difficult to get any momentum at all unless you can get a bunker or something. That map you saw there has one building that has a flight of stairs in it. If you can get up it, you can sometimes hold it for awhile and get a rhythm going before anyone gets you. Due to the nature of the game it can take awhile for someone who knows you're there to make it back to the place since people are constantly popping all over the place. Even if they get back over there they might figure you're not in there anymore and forget about it. I've been able to have runs of 5-10 kills which is far better than simply running around.
Team death match has been my favorite so far. One of the popular maps for this is called "Sweden". There are 2 opposing bases with 3 entrances/exits each. A central bridge, a couple sniper buildings, and lots of hiding spots to get the drop on people. Controlling the bridge usually means your team will win. From the bridge you can quickly move between all 3 entrances and exits (overlooking 2, direct access to 1) so a good team can cover everything and really pen in the other team. I played for a couple hours with a fellow calling himself 바보 (Korean for fool) followed by some other characters I forget. Very good and most maps were a duel between him and I for top spot. He won slightly more than me, but I had some very good games both on his team and against him where I started the game 6 or 7 and 0. In addition to your team winning the match the players individually compete for the most points during a game, and the game will inform you if you're currently leading. Annoying if two people are dueling like we were. "You've taken the lead! You've lost the lead! Assit! You've taken the lead!" it can get pretty rapid fire until someone pulls away.
Experience works interestingly in this game. You get XP based on the rank of the person you kill, assists (more than 60% damage to someone and then someone else kills them), head shots, and stacking kills. Each time you kill someone you get 5 seconds to kill another person to have it become a "multi-kill" twice I've hit 5 and once I hit 6. The progression is something like: multi, triple, monster, ultra, crazy then at 6 it just said "6 kills!!" Kind of a let down. It says that you get a big XP boost if you get 5 kills in a row like that.
I also got to make a new character and find out more about buying things. Characters and guns are permanent. Not rentals. Armor is a rental. Characters let you assign 7 points to various stats. To make an assault guy, a sniper, etc. I'll attach a screenshot below. Guns get repaired, and armor has to be bought every 30 days. It is nice to see guns as permanent. If you don't play for awhile you'll lose your armor and have to but it again, but at least your guns will be there. Some armor choices can be made between adding stuff to give more defense or more speed. Grenades aren't rentals but they can't be repaired. I assume when they run out you need to buy a new one, but it's okay, they're pretty cheap compared to everything else.
After playing this some more, I think I'll continue playing it. I didn't think it would stand-up to AVA, but it has proven more interesting than I initially though. So just because there is some girl holding a gun in an entirely inappropriate way on the website, don't pass the game over. You might be pleasantly surprised. I still don't know what "Justice for all" means. There doesn't seem to be any clear-cut sides in the game and they're referred to as mercenaries. The English in game is great. I didn't notice any weird sentences, so I think they've paid to have this professionally translated. At the time of writing this I'm ranked 158th globally. So this really isn't that hard of a game to get into.
