If I could give this game a middle rating I would. The core gameplay loop of light stealth and action planning is good, nice controls, responsive, and explained well. However, there isn't much loot variety and certain items you always need at high levels, such as the ability to turn off shields on otherwise invulnerable enemies. While you can unlock items as you progress, the unlocks are just improvements on the base item type, such as having a higher ammo capacity. Once an item is unlocked you directly buy it on your next playthrough. So while you can restart with a different character, that different character essentially plays the same as your last, quickly buying or finding the same gear you had last time. It eventually feels quite repetitive.
I really love this game. Most of the gadgets are really fun to use, especially in combination with others. It's genuinely intoxicating when you get a self-charging gadget for the first time on a character. A 5/5 rechargeable sidewinder is cool, but a 3/3 self-charging sidewinder makes me use it 10x as often. I always grow to appreciate the gadgets more when I have that freedom to experiment even more. I think the only real misses for me are the acid trap, glitch trap, explosives, and loud guns. Even these are still useful though. I've never used an acid trap because I feel like armor piercing weapons are way more accessible, and I've never been in a situation where I get acid traps first. Glitch traps are mostly something I just don't have much experience using. I can imagine the utility in ejecting a defender into space or one guy with a shield I can't disable. I just don't get them often enough before I have other solutions. There's also a decent number of windows which can solve a similar problem cheaper. Explosives and loud guns are a bit different. I don't feel like it's ever really worth triggering an alarm unless you're on low level areas or killed the pilot. If it's the latter, you're probably most of the way through the ship anyways, so carrying some tools that are only useful in the last 3rd of the mission feels pointless. Using an throwing a long/short blade feels basically just as powerful as any gun. I played this game pretty shortly after release, before they added Contractors. When I came back to this game after that update, I did really hate them. They made my chill game so difficult. I do get it now though. The jammers honestly don't seem that bad anymore. Half the time, they setup one or two areas then basically run into me. It's more about knowing there is one to try and rush forward a bit for. Defenders are probably the most annoying to me, but I think they're an interesting challenge. I think trackers are the one I remember the least, cause I didn't run into any in my most recent session. Overall, game fun. Watch a video if you're on the fence
So I am late to the party here, I bought this game back in 2020 or so, opened it, liked the vibes but couldn't get past the 2d top down art style. I thought "hu, neat it was 5 bucks so I will get to it eventually." Well friends, I have gotten to it. The addition of achievements might have been what I needed to have some goal for how to pursue the endgame of Heat Signature. There are a number of achievements that coax you into certain playstyles and I am having a blast chasing them. This game is somewhat dated in the textures and UI department but I don't find that it detracts from the experience at all. You can be a... Space ninja Space hitman Space thief Pacifist Ghost Communist? Space Hippie And so much more. I would recommend this game as a fast-paced puzzler more than anything, it scratches the hitman itch for me and I find that the missions very much push you into being extremely cautious where one mistake can blow your run. The overall gameplay loop is sort of a looter-shooter where your characters and gear are temporary so you should use them wisely. You gradually liberate the galaxy until you can purchase really powerful items quickly! I am almost through my first run of the full game at ~20 hours or so and I can't recommend it enough!
I don't write many reviews, but I've played many games. This game is SO CLEVER, it's been literally THE PERFECT addition to my steam deck - compat shows ? but its PERFECT. I love the RNG, I love the strategy, I love this game, it's one of my favorite games probably of all time next to C&C
The best review I can come up with for this game isn't a review. Rather, it's a story of the funniest moment that happened to me while playing. I entered the target ship on a VIP mission. I need to capture a target NPC. If the alarm goes off, not only will the guards get more dangerous, but the VIP will run to a teleporter room and escape. In the first room, I acquired an explosive. I never use explosives, preferring non-lethal means. Feeling a bit naughty, I throw the explosive into a corner just to feel something. Big mistake. The room is blown clean open and the ship alarm goes off. At this point I've basically failed the mission, but I run forward and see the teleporter in the second room, at the end of a hallway just on the other end of the door. Perfect! I'll wait for the VIP to get close, open the door, and nab them before they can teleport. So the VIP shows up, I open the door.... ...and a non-lethal turret I didn't notice shoots at me. Now I've definitely lost the mission, right? Au contraire! Because this all went down in a hallway, the turret instead beans the VIP in the back of the head! The VIP slides on their chin past the teleporter, through the doors (which close behind them), and stops at my feet. Heat Signature is a good game, and you should play it.
