Put together John Carpenter’s The Thing, the old Rampage game, and mobile gaming, and what do you get? Probably something like Alien Invasion: RPG Idle Space.
Alien Invasion: RPG Idle Space tasks players with invading a facility – and perhaps, eventually, the world. You’ll need to raise your alien from a tiny, squishy conqueror to an eater of worlds by consuming humans, upgrading your abilities, and completing quests for your brethren. Alien Invasion: RPG Idle Space is available on both the Google Play Store and the App Store.
Alien Invasion: RPG Idle Space is a very simple and intuitive game. However, if you’d like a sneak peek at the first five levels, as well as get an idea of what to expect and what to look out for, read on for some useful tips, tricks and strategies!
The First Five Levels
Progression in Alien Invasion: RPG Idle Space can be divided into levels. As your alien eats people and grows, you’ll unlock new zones, each with its own opportunities and hazards.
- Command Center = deposit loot and heal
- Exchanger = trade alien eggs for meat at a 1:100 ratio. Do not do this.
Your alien’s first level introduces the basics of the game, namely, how to move around and capture humans. It also houses two basic buildings – the Command Center and the Exchanger.
The Command Center (note that it doesn’t have an official name) is where you go to deposit your spoils, and if you’re injured, it will bring you back up to full health. If you die before banking your loot at the Command Center, it vanishes – so don’t overextend!
The Exchanger is where you can trade alien eggs for meat, at a 1:100 ratio. I don’t recommend doing this, as you need crystals not only for strengthening your base abilities, but also doing side upgrades at the black market. And while 100 meat might sound like a lot right now, it’s a drip in the bucket compared to your income in just a few levels. You get alien eggs from special humans; in particular, the guy with the jetpack is a great source of early alien eggs, and he can sometimes show up in area one.
While meat pickings are slim in area one, make it a point to watch ads whenever you can as they give lots of the stuff. The progress you make in the game also determines what items can appear in the ad chests.
At this point, I’d suggest focusing on raw attack power by increasing the capture rate of your alien. If you have the meat to buy an extra tentacle, do so.
- General Kustov = find octopus aliens to passively generate humans that drop cash shop currency. Respawns every 3 hours. More aliens = more humans.
- Farm = idle meat production. Can be upgraded. Has an upgradable cap; when fully upgraded, this fills in about 15 minutes.
Getting up to level two unlocks the door west of your initial position. This not only gives you access to more facilities but also gives you better humans to capture – if you have the attack power to do it.
The most prominent feature that area two has is the mutant general Kustov, who’s waiting just above the entrance. He needs your help getting back these octopus alien things. Take note of this quest, as the more of those aliens you free, the more green crystal humans will spawn every 3 hours. This will allow you to go full F2P if you’re willing to stomach the long waiting time.
The other thing that area two unlocks is the Farm. This structure is on the leftmost side of area two, and passively generates meat that you have to collect every ten minutes. The farm also benefits from two upgrade trees; one increases its income per minute, and the other increases its maximum capacity. Together, these two will allow you to generate 3500 meat roughly every 15 minutes. Whether you use it or not is up to you.
Because you need to move back and forth between feeding grounds, I suggest you start investing in quality of life upgrades, such as attack radius and movement speed. You should also start upgrading stomach capacity to make your trips more worthwhile.
- Black Market = trade alien eggs for upgrades and alien tier up.
- Bots Shop = automate meat production. Works even when you’re offline, so this is very important. Delivery bots are also nice.
- Pink DNA farming spot at the top right of area three.
- Good meat farming spot to the right side of area three, in a small cove.
- Alien egg farming spot at the top left of area three.
Level three opens the door northwest of your Command Center, giving you access to the Black Market.
Remember when I said not to spend your alien eggs? That’s because the Black Market gives you access to potent upgrades, which is great if you’re starving for meat. But that’s not all the Black Market does – it allows you to upgrade your alien itself to the next level, giving it new features (such as pincers) and increasing your raw stats. Note that to increase your alien’s tier, you need to have a minimum amount of Black Market upgrades – the first tier up requires 50 upgrades – as well as a healthy amount of both meat and alien eggs.
Apart from the Black Market, you also gain access to the Bots Shop, which allows you to automate meat harvesting, even while offline. Said bots will not only capture humans for you, but also help you make less trips to your base by going to you and depositing a portion of your loot.
Do note that individual bots are weak, so you’ll need to heavily invest in this to start seeing worthwhile gains while offline. That said, I highly recommend dumping a lot of meat here – the more AFK gains you have, the better.
You might also notice a pink DNA sign at the northmost end of area 3. This sign heralds the presence of humans that drop that kind of DNA; in this case, it’s the blue glowy guys in the middle. Harvest them whenever you can.
To the direct right side of the entrance is a small pocket of humans. These guys are notable in that they have very high meat drops relative to their capture difficulty. This makes them a priority target for any new level 3 aliens. Do note that because they’re so choice, they have a longer respawn time than usual. If you have a bot army, they’ll also prioritize locations like these.
One other spot you should take special note of in area three is the uppermost left, near the area five door. There are a bunch of heavyset guys with packs on their backs, and each of them gives upwards of 400 meat and an alien egg. Congratulations, alien eggs are now reliably farmable.
The grind from level 3 to level 4 is quite lengthy, so take the time to really get your upgrades going. If you haven’t bought new tentacles yet, do so. I also recommend pumping your HP, speed, and capture radius at this point.
- Another farm with a bigger cap.
- Aggressive humans start appearing. Work on your capture rate, speed, and optionally HP. Learn to kite – a basic strategy is going in small circles.
- Teal DNA farming spot in the middle left of area four.
- Teal DNA humans’ minions give lots of exp.
Level four is when the humans start fighting back.
And don’t think that they’ll zerg rush you because they won’t. Each individual human soldier is a powerful warrior, and even if you’ve invested in HP, they’ll take you down very quickly. It’s best to get acclimated to hostile targets as soon as possible.
If you want to pick fights immediately after leveling up, you’re in luck – the first group of humans behind the newly opened area 4 door in your starting area is composed solely of fighters. Use them to get used to capturing highly mobile and aggressive targets and upgrade your alien accordingly. If you’re practicing, keep in mind that dying drops all your unbanked loot, so don’t pick fights until you’ve deposited your precious alien eggs, diamonds, and DNA!
I find that the best way to engage in combat with humans is to upgrade your speed, capture speed, and capture radius. Aggro as many as you’re comfortable with, then lure them to an open area and go around in small circles. Be sure to keep them inside your capture radius, as even a split second out of it resets the capture bar entirely.
Your upgrades will likely start asking for teal DNA, which you can start harvesting in area four. Don’t expect to get it without a fight, though. While the glowy guys on the left side of area 4 don’t put up a fight, their minions will, so gear up and practice. As with the pink DNA guys, harvest the teal guys whenever you can.
As a side note, the teal guys’ minions are a lot squishier compared to the guys at the lower end of area four. And while they drop a lot less meat, they give great exp relative to anything else you’ve fought until this point.
Once you’re used to fighting normal human mooks, it’s time to tackle the big boys. Before you do that though, be sure to grab the quest to open ventilation shafts from your extraterrestrial comrades in area four. When you’re ready, head back to the upper part of area two.
You’ll notice that the door to the right side has been unlocked, and one of the ventilation shafts is in there. Unfortunately for you, this area is guarded by incredibly tough human mooks, and facetanking them is not an option. Use your newly-learned kiting skills to draw them out – one or two at a time – until you’ve thinned their numbers enough to pull the cover off the ventilation shaft. I recommend just getting the quest done, then never coming back here.
If you’re still starving for meat, there’s a new farm on the right side of area 4. This farm runs on the same mechanics as the one in area 2, except that it needs more meat for its upgrades. The plus side is that a fully upgraded area 4 farm yields 35k meat every 10 minutes, which is a not inconsiderable amount.
- Agents in the upper area of area five. Avoid them unless you like dying.
- Cracked egg farming spot in the lower left zone of area five (above area three egg farming zone)
- New exchanger on right; eight cracked eggs for one intact (spendable) egg.
Area five will be your new stomping grounds once you hit level five, and it’s here that the kid gloves really come off.
You’ll notice a distinct lack of aggressive humans, compared to area four; in fact, there are only two enemies here that will attack you. Said enemies are the Agents, two guys in tuxedos who not only drop a hefty amount of meat, but also two alien eggs and white DNA. The catch? They’ll instantly murder you as soon as they see you. They’re fast, they’re sturdy, and they hit for double-digit damage. The worst part is that you’ll also get a quest to capture two of them. I’d suggest putting this off for later.
Area five also comes with another exchanger on its right side, this one for trading in eight smashed alien eggs (which you can’t use) for an intact one that you can use. The best part? The guys that drop these smashed eggs are just above the area three egg farming spot.
All the humans in area five are incredibly tough, so if you haven’t upgraded your alien to the next tier yet via the black market, do so. This will not only uncap the base upgrades but also give you two new important upgrades, namely damage reduction and slowing attack.
Your Invasion, Your Rules
Alien Invasion: RPG Idle Space is, at its heart, an idle game, and time is on your side. Take whatever approach you want to conquer the world; after all, in lots of alien-based media, conquest is inevitable, and as the invader, you’re free to do whatever you want.
