Serious Sam 2 doesn't take itself seriously on the surface, but as a hardcore fan of tough slaughterfest FPS bullet/melee hell gameplay that this franchise is known for, I give this game a serious thumbs up.
I am by no means an inexperienced player so trust me, if I say a game is hard it's probably tougher than what you'd expect and SS2 is surprisingly difficult which is a refreshing revamp of the series that delivers exactly what real fans wanted. Normal in SS2 feels more like hard in SS1 a lot of the time and the tricks up the dev's sleeves perform nicely and will have you strategizing more than shooting on various occasions.
The weapons have a pleasant, balanced feel to them that encourages you to get creative and never have an ultimate go-to. Yes some weapons are of course better for certain situations than others, but seldom will you feel like you'd be screwed if you didn't have ammo for a specific weapon. The Devs are good about giving you the ammo you need, and you see ammo packs, large health and powerups much more often in this installation of the series making way for big fights equally more often.
Enemies are what you'd expect, but there's some awesome additions especially ranged enemies. In the first game, most of the ranged attacks were projectiles but in SS2 there's more rockets and more bullets to force you to kill fast, fast fast and prioritize targets effectively if you want to stay alive for long. Also, there's more strategy involved in taking down enemies this time around. One of the first enemies has a shield that it'll drop when you shoot it, but I'm pretty sure making contact while before it drops the shield does more damage. I'm not positive about that though. Either way, more strategy difficulty and satisfaction.
The environments are pretty epic and vary just enough to keep you happy without getting overly obnoxious. There's moments where you say "Damn, this game had amazing graphics for it's time" and it did, not only that, but the engine is super optimized. I have a pretty aweful system and I'm very impressed by how well I can run the game.
Serious Sam 2 has stupid humor that made me laugh and facepalm simultaniously. You have to not take it seriously, and with the massive amount of bloodshed that goes into this game, the comic style of the game and it's visual design is commendable on the part of the Dev's. I will say that I prefered the darker style of SS1 but where this game lacks in any area for me it makes up for in gameplay. The gameplay is just awesome.
This game is satisfyingly challenging, fun, surprisingly not repetetive for the very basic concept behind it, and goes down in my book as a must-have for fans of games like oldschool doom, painkiller, and other doom clones including serious sam 1.
I'd pay $20 for this game, and I paid $10. Maybe I'm a sucker for games like these, but if I am then I gladly sucked this game right up and I give this a total of 7/10. Not bad for a game that's literally like: Here's baddies, here's gun, here's excuse oops I mean story, go kill. *Pounds chest*.
