I am slightly conflicted when recommending this game. People may enjoy different things out of a game than I do.
As per usual with my reviews, I'll take my time to lay out why I recommend this game.
I bares noting that I finished the game on the ultimate hardest difficulty, only available to owners of the Scorchers DLC.
Rage has a combat system that I regard as fun. Especially in the beginning, assuming you went the hardest difficulty, the game quickly plays the resource game. I was challenged often to use my ammo sparingly, keeping my real good guns for emergencies.
Money is on short supply as well, so it becomes a balancing act of fighting and earning money to cover your costs.
The really strong weapons, like the shotgun (which remains a solid option throughout the game) will run out of ammo fast if you only use that. Sadly, this balance can be ruined by an exploit. It's a little convoluted, but workable. I tried it and felt I ruined the experience a little bit for myself, having large stocks of ammo now. There was no way I would waste 500 shotgun shells halfway through the story. If you feel honorable enough, you can avoid doing it.
The combat itself is enjoyable. The guns feel like they have weight, and rightfully so. Hitting something with the full blast of a shotgun will annihalate a small enemy, and stun normal ones with a second killing them. Using a grenade to stun the really big enemies is a valid tactic to then unload shotgun ammo into them.
But if you play on a hard difficulty, you'll not be running and gunning. In fact, much like the enemies, you'll be looking for cover often and peak out to exploit their unfortunate positioning, if any.
And if you get shot? Well, the revive mechanic is there to save you, zapping you back to life if it has a charge.
This is a good mechanic to balance the cheap lucky shots the enemies sometimes like to dole out.
Storywise, the game is solid. It's not the best, but it tries to be comprehensible and cohesive. It feels like a potential that wasn't fully tapped into. This is noticeable in two things. One is the missions, where they objective is little more than progress through area's through, well, shooting and reaching the end. Then make your way back, often using a shortcut.
But the worst part is, however, it's ending.
Now, I would not skip on buying this game because of it. It's literally the last mission that is completely ♥♥♥♥. You break in a facility, spend a few hallways killing and pushing buttons and then tough out a minor gauntlet. No final boss, nothing to really write home to.
Everything before that mission seems fine and as the same quality as the rest of the game. Which makes it even more mindboggling. I cannot fathom why something like this was ended in such a way.
It begs the question if it wasn't rushed or something.
The same devs made Wolfenstein: The New Order, and I can taste some of the influences. Taking cover, the guns feeling good... But while Wolfenstein was more like a hallway shooter, pushing you forward into levels constantly, Rage has a bit of an open world aspect. Not as vast as you'd hope, but big enough to rummage around and see the sights. However, mission handling and such always happen in cities and such. Even races.
Races are moderately enjoyable, and are required to upgrade your vehicle. But all in all, they're not something that ultimately stands out as extremely enjoyable, but a good enough time waster if you feel like trying. The races vary from time trials, racing combat to hunting random checkpoints that appear on the map. The enemy AI, especially in high difficulties, can be a real challenge though. So if you want those achievements, maybe do those on a different difficulty.
I found Rage a worthwhile experience. The combat and gameplay, which matters more to me, felt good. Most of the weapons fit archetypes that you should be familiar with, but most of their design fits the theme. Except the shotgun. Damn thing looks like a modern polished weapon in a world of rusty and dusted weapons. It doesn't look high tech either like the late game villain's weapons do. Odd one, that.
The exploration and story could have been better, but the atmosphere is very well done. There's lots to do, a few things to gamble in a few games, and tasks to do. The people in the cities don't repeat their lines, and often have interesting things to say. Not to mention that they seem to be all named. As if they were placed by hand.
If the positive aspects I've described call to you, then Rage may be a worthwhile experience for you as well. As a game of age, it'll now be more often on sale, so be sure to grab it at your convenience.
And if you want a game where the combat also feels just as good, Wolfenstein: The New Order will be the next game I may heartily recommend.
