I can see why this is classified as one of the better HL2 mods; the atmosphere is great, the combat is more weighty than the vanilla game due to the premise, and some of the set pieces are incredibly interesting.

It's not without flaws, though; both of the bosses are bad, ranging from slightly annoying to not even knowing if you're progressing till it's already over, and playing on the difficulty that makes the game most interesting leads to it being so wholly unfair that anyone who played on it would be forgiven for either cheating or giving up at some point.

Okay, gonna be real with you guys. Aside from the funny memes surrounding it, this game is absolute crap. Even by mobile game standards, it fucking REEKS.

Which is a shame, because the core gameplay is kinda fun! But it doesn't mean much when your game is riddled with the most confusing and predatory unlocking/MTX system I've seen in any video game, poor controls and performance, and ads every five seconds, making it nigh unplayable in some ways. While I can't exactly blame drunk me for spending money on the ad removal IAP, I still want to smack him upside the head for wasting $2.67 USD of my hard-earned money (Google Play credit, in his defense), regardless.

The game gets REALLY bad around level 40 or so, requiring almost superhuman reflexes to even get past the obstacles, and this game seemingly doesn't have a way to cope with it. For all the asinine ways the game does to unlock and upgrade your gorillas, it sure doesn't have any powerups to help out not-so-good players. It's saying a lot when a hard-boiled STG player like me is having severe issues with this game.

If you come across an ad for this game, laugh at it and move on with your day. Don't waste your time with this game (and money, maybe) like I unfortunately did.
