D.E.E.P Impact


If the Ludum Dare embed gives you an error, play it on itch.io

A retro-arcade-style shoot em' down where you can't always see the sub-terranean terrors threatening civilization! Deploy the experimental D.E.E.P. combat vehicle and its array of drill missiles against the vile underground Tectoids. Scan the earth using ground-penetrating radar and tactically carve out the terrain with high-explosives! Then, once you've caught your breath, count yourself lucky you don't need real quarters to play.

*WARNING: THIS IS A HIGH-DIFFICULTY GAME! DON'T BE DISCOURAGED IF YOU KNEEL BEFORE THE TECTOID THREAT!*

We don't have an online leaderboard, but we'd be pumped if you posted the highest wave you made it to in the comments section of our Ludum Dare page! There's even a secret phrase you'll learn after beating the 10th wave that you can post for maximum bragging rights!

Controls


Move D.E.E.P: A and D

Use Weapons: Left and Right Arrow

Use Radar: Hold and release Down Arrow

Use Arsenal: Up Arrow when near arsenal

While the D.E.E.P. cannot take damage, each Tectoid that escapes to the surface increases global Mayhem. After the sixth Tectoid gets loose on the surface, it's curtains for humanity!

Your starting weapons are the *Basic Drill* and the *Timed Drill*.

Changelog


*1.01*

- Switched starting weapon from Remote Driller to Timed Driller

- Added a secret passphrase for those who beat the game

- Bugfix: Only one conqueror can now spawn at a time

*1.02*

- Show mayhem level on upgrade screen

- Add volume controls to main menu

- Lower default music volume

- Change upgrade text to include exact values (e.g 10% instead of "small change")

- Show names of weapon when switching weapons

- Show upgrades chosen in game over screen

It took me a bit to fully understand what I was doing, but by the end of it I actually quite liked this! There was some interesting strategy in the various weapons and what benefits they gave you. I really liked how you could blow up chunks of the ground below to give little previews of where the enemies were without the use of the radar.

I feel like having the radar identify enemies as it was firing (as opposed to just when you let go) would help a bit with the difficulty here. It was hard to catch enemies even when I knew generally where they were.

It was a litle bit hard at first and then i started to understand and had fun ! A lot of time my drill exploded right under me but it seems i was just really lucky 😂. I think the radar could have a small boost but its still playable and enjoyable. Well done !

This is a lot of fun. I really like the weapon choices.

Pretty cool! Everything started to click once i realized one of the missiles expose terrain/enemies, which is honestly a really neat way to let the player multitask finding enemies through both that method and the radar.

First off, I suck at this! I dig the minimalistic style of the game, aesthatically pleasing enough, though the "arsenal" font still irks me! Gameplay was solid and fun, really addictive infact, though hard. I appreciate that there are several types of enemies and weapons. I would have liked to see different types of sonars maybe, like one that moves far more slower, but wider etc perhaps? Anyway, marvelous little game!

Thanks! There was definitely a lot planned that didn't make it in. We're happy it's fun as-is!

This was a lot of fun to play. It was a bit difficult to figure out the controls, but once I did I had a great time with it. I really loved the look and feel, but it was a bit difficult to tell the drills apart

Good chip tune music, with music theory behind it. I enjoyed the scanning the scanning mechanic a lot, it combines the fun of exploring fog of war with an arcade game.

I like how there were different strategies with the weapons you can pick, and the upgrades that you choose. It was a little difficult to determine which weapon did what at first, and was hard to tell them apart. But once I got the hang of it it was quite fun. The music got across the frantic feel very well.

Probably the most fun game I've played so far! Unfortunately pretty hard to play with a 60% keyboard (I don't have arrow keys) which tbh is my own fault.

My strategy was to go double remote charge and rush to blow up a line at around 50% height, then go from there.

I enjoyed playing the game :) Sometimes I only saw Tectoids once they were close to the surface and couldn't do anything about it, this is a bit frustrating.

I enjoyed the game, though I didn't manage to complete it. I felt like the radar was mostly useless, I felt I did a better job just by spamming the timed miner until I got a good amount of visibility. My biggest complaint is that I would lose after getting pretty far by not being able to pinpoint where the dodgy enemy was (whatever it was called) and got an instant game-over from it emerging. Especially if it was one of the first enemies to spawn in a wave when I had very little vision.
