A start to one of the best Tekken spin offs ever and if you've played Tekken 3 before then this game is pretty much that but much better.
This game takes everything people loved about Tekken 3 and cranks it up tenfold with improved gameplay and impressive visuals and CGI even for it's time and beautiful soundtrack to listen to go along with it

First off the roster is absolutely stacked even for its time having a total of 39 characters consisting of characters all the way from Tekken 1 to 3 (minus Mokujin and Gon) while adding some new ones that's exclusively for this game and all of them have different endings that are nice to watch and the character models are nice to look at like Yoshimitsu or Jin or Kazuya, even though their designs are from previous Tekken games but they have costumes that're only on this game and even years after its release, the character models in this game and still hold up quite well and the animations for each fighter are still buttery smooth and although these animations and even sound effects are all taken from previous Tekken games so it's basically like a remastered version of Tekken 1-3, it still captures the fluidity and power of each move with precision.

Now the real star of the show or this game rather is obviously the tag system with the player being able to switch between characters on the fly which adds a whole new layer of strategy to the fights and completely change the flow of a match. One minute you're getting your ass kicked and then you tag out to heal and let your partner do the dirty work or that moment when you're down to a sliver of health and then you manange to pull off a sickass clutch tag throw combo and win and it's just so satisfying.
And the tag throw animations in this game are so satisfying to look at especially the special ones like seeing the way King would toss his opponent aside only for Armor King to then pick them up and slam them to the ground or seeing Kazuya headbutt someone and then Jun starts elbowing them when they're on the ground and it is just a sight to behold.

Do you want to become a Helldiver and spread Managed Democracy and to make sure you treat your enemies with a nice cup of liber-tea but you don't have the right hardware (or money) to do that? Well this game is just for you, soldier.

The big difference in this game when you either play the game or look up game footages on the internet is obviously the change in visuals and perspective. This game plays just like Helldivers 2 if you played that first (which i'm sure a lot of people did) with you moving and running around freely in an open space and shoot enemies while also completing objectives but instead of third-person and a mix of first-person perspective (when you aim down sights), this game has more of a top-down perspective which in a way kind of reminds me of Alien Swarm but instead of exploring labs, abandoned ships, etc. and killing bugs on the way, you're in a very open space and when you aim down sights its still on a top-down view but you're guided with both your cursor and a laser sight instead.

Another big difference is the visuals of this game having an almost cartoonish look to it in both environments and other models whilst Helldivers 2 has a more realistic and gritty and slightly vibrant look to it which i very much prefer but unfortunately the game is not on PS4 if you only have that and you only have a low-end PC but you want to jump in that Helldivers hype then this is your only option.

What's interesting about the visual change that also correlates with the perspective change is that with the top-down view and cartoonish artstyle, the environments don't really look that appealing hence why Helldivers 2 opted for a more third person and realistic look which not only can make the planet you're on look beautiful but also can let you see everything from afar like objects or enemies or even moons or other planets hovering above you, at least i think thats why they shifted to that perspective.
This shift in perspective can also make combat situations feel way more intense as enemies usually come in hordes so they're very much in your face and sure you can say that this intense feeling of being overwhelmed by the enemy is present in this game.

Overall, if you want to pick up Helldivers but don't have a 9th generation console or a powerful PC to boot up the second game then this is a good alternative for you. Both games share similarities in terms of its gameplay, difficulty, weapons, stratagems, command inputs for your stratagems and of course the good ol friendly fire to not only fuck with your friends but also yourself.
