Standards on my Rating:
1. This game is often regarded to the game, "Call of Duty Modern Warfare 2019" so I will keep that in mind, and that gives a - 1 star on my book, 4 stars for the fact that the gameplay is smooth.
2. The fast-paced gameplay is matched with the animations that transition to one another keeping in mind game balance, what I mean by that is that you can't be a sniper and then quickly transition to your pistol, you can't be an assault rifle that harrasses enemy positioning and then just quickly use melee. No, there is an element of "game balance" where every maneuver has a vulnerability.
3. Keep in mind that I had played this game for only 3 days, and then switched to Call of Duty Mobile as my main. This is due to the fact I am not really an advocate of the kind of pay-to-win aspect that they have. I may refer to General References, and I may refer to the general aspect of the game. I'm a casual at the game.
Personal thoughts on the game:
This game's philosophy has 70% "This isn't pay to win if you can grind for what you want." This game also has 30% "If you pay right now, you can gain an unfair advantage over your enemies." If you're up to the kind of game that can adapt to the circumstances of enemies having dual-wield SMG whilst you can only unlock a variant of said SMG without the dual-wield. (This was months ago, I am pretty sure they balanced this out) However, you can still beat enemies with the given circumstance that the TTK (time to kill) of each weapons are similar to each other on the chest area to the head area. This game isn't an advocate of "Pay-to-win armor sets that give an unfair advantage to opponents" that I see from mobile FPS games from time to time. (At this point in time)
In conclusion to what I had just said:
"Basically your enemies can pay for advantages, but you can still beat them 1:1 ratio of the time given your circumstances, if you have good positioning, maneuver, aim and game sense."
PROS AND CONS OF THE GAME
(Keep in mind that I will regard the developers' circumstances in real life given the Ukraine-Russia War)
Pros:
1. The pay-to-win aspect of the game is bypassable due to the time to kill of weapons.
Let's say that a player has a dual-wield SMG that is unlocked by paying. You can bypass this because snipers have one-shot capabilities, other SMG weapons have similar time to kill, assault rifles dominate mid-range gunfights, or you can just straight up melee enemies. In general, the game is fun to play in this manner. A free-to-play player can survive 1:1 ratio against pay-to-win players due to positioning, movement mechanics, skill level of weapons, and game sense.
2. Movement Mechanic
This game isn't just "Aim-and-Shoot." You can just slide a corner and then slide-peek your opponent, you can slide-jump to make yourself hard to hit. You can bunny hop whilst shooting to make yourself harder to hit. There is an entire genre of this called "Movement shooters" where Titanfall 2, Apex Legends and Quake Champions generally reign dominant. The correct use of movement + shooting depends on every situation and rewards you for it.
3. Lack of SBMM
That means Skill-Based Matchmaking and is hated by gamers to the fact that a player can be graded the same way as veterans, so the skill-gap and experience-gap is insane. In Combat Master, every skill level of players is welcome in almost every casual lobby. This gives the sense of learning from your opponents. This is to say though that also Pay-to-Win players are also present, but is bypassed by time-to-kill of weapons.
Cons:
1. Game Balance Takes a While
The game's META isn't as refined as Call of Duty Mobile given the circumstances of the developers. What I mean by that is that the weapon damage, switch time to pistol/smg/melee/launcher from your primary weapon or other game mechanics that affect game flow isn't as refined as Call of Duty Mobile, but that makes up for the movement mechanics, current gunplay and map design. (Enclosed spaces don't really benefit launcher long shots or close quarters combat doesn't really benefit snipers that much)
2. Pay-To-Win Aspect (Bypassable due to weapon time-to-kill)
The pay-to-win aspect of certain weapons unlocked behind a pay wall gives unfair advantage to players that are free-to-play. If you have a variant of a weapon, but the payed weapon has a distinct advantage such as dual-wield, there's a problem. However, that problem is bypassed by the fact that the weapons in the game are having close TTK (time to kill to each other) and one shot weapons require skill.
Personal Conclusion:
I really wish I could say "The game punishes players that give unfair advantage to players" such as CODM that punishes operator skills, since grenade launchers don't work on confined spaces to the risk of getting caught of the massive splash damage or the fact that operator skills are time-limited per use. That mechanic is balanced to the fact that every weapon is free there and the time-to-kill is refined per update in CODM.
That aside, the game is generally fun and Casuals can have fun alongside competitive players. There isn't a skill-based matchmaking aspect of the game and I can say that because different skill levels are present in one round everytime. Players can learn from each other this way.
Overall, a good quality game minus the pay wall + the fact that the original ideas generally come from Call of Duty Modern Warfare 2019.
