The Killbots of Cavern Station

by Gilvado - Competition Entry

The Killbots of Cavern Station is a real time semi-tactical game. Use cover to kill the evil killbots.

Check out the timelapse at:

Flixel and my own custom collision detection optimizations
Tile Studio/Graphics Gale for pixel art
Sfxr for sounds


WASD controls the camera.

Space bar to switch between your different squads
Click to send squad to location.

Squads will take cover behind any cover (white blocks) that their control rectangle touches or contains.
Squad members shoot automatically.

If a laser crosses cover, it has a 75 percent chance of hitting that cover (unless it's cover that the squad member is attached to, of course).

Tanks cannot take cover.

man, they tear you UP on level 2. that stuff is bananas! awesome job.

smx says ...

Pretty hairy on lvl 5, but still fair.
This is what LD is about in my book. Gameplay first, who cares if the playfield only consists of rectangles. AI is good enough to try different tactics, upgrading and the tank add a lot to the replay value. Definitely one of my favourites so far.

dstrysnd says ...

It's Highwaymen, but better! Highwaymen was one of my favorite LD games ever. I'll be playing this much more!

ondrew says ...

Cool game, really good gameplay and lot's of fun.

Radix says ...

Man, this is great.

Matt Thorson says ...

I REALLY like the strategy aspect of this game - moving from cover to cover and such. Doesn't really use the theme at all, but it's really fun and interesting. If you worked a lot on the visual/audio and added a tutorial, you could easily get a sponsorship for this.

jplur says ...

High marks! This is a great implementation of squad based shooters. An amazing amount of gameplay for 48 hours.

Doches says ...

5/5 for innovation, and similar marks for fun, because the squad-based cover mechanic is flawless. Graphics are simple, but don't detract, and the entire package is just perfect.

Wiering says ...

Very nice game!

shanecelis says ...

Wow, very fun, innovative game.

doohan says ...

This is a fantastic game. The squad mechanics are great, and this game kept my interest right through to the finish. Looking forward to seeing more of this at some point!

Endurion says ...

Now that's a really good idea.

And fuck it, they are nasty in level 2. This can be made in a real awesome game!

Entar says ...

Cool game, fun strategy elements. Reasonably intuitive to control - only complaint is that it can sometimes be a tad tough to see which units you're controlling. Otherwise, cool game, would like to see some music and improved graphics with this.

nilsf says ...

I didn't like the way you had to move the camera around, but apart from that it's an awesome game. Good job.

mjau says ...

I somehow missed that the camera could be moved at first. This got a lot better once I figured that out =). It's great.

Almost says ...

Pretty great, Pity that the theme wasn't swarms. The controls felt a little weird, but weren't a serious issue. AI seemed to be good, fleeing when outnumbered, and attacking when in full force. Levels, upgrades, etc all add to replay value, which is good.

afterthought says ...

Sooo good! It needs more art, better unit AI, more sound, more units, etc, but for a game concept/prototype this is absolutely perfect. I didn't have a whole lot of trouble except once in an earlier level. Just as fun as DoW2 in a lot of ways. I hope the tanks have less armor in the rear :)

I also never noticed you could move the camera, but that's okay.

Comtemno says ...

Good! Really good. Difficulty is always nice to have!

erik says ...

That was a lot of fun. It took a little while to adjust to the controls, and figure out what was going on, but then I really enjoyed it. It's not easy to make multi-unit control work in such a short time frame, but it did work well enough to play strategically. Upgrades are always fun.

It's a nice improvement over what you did with Highwaymen. The game play doesn't have a strong connection with the theme, but the narrative helped make up for that. Good job.

Jonny D says ...

I don't know why people are talking up Level 2... :)
The difficulty didn't seem to scale very well, but the game was good overall. I would have liked more upgrade choices and a display for the number of guys in each squad. After exhausting the upgrades rather quickly, even Level 5 was easy. The Tank is a little overpowered because the enemy doesn't react much when you send it right behind them for easy kills.

noonat says ...

This is friggin awesome. The graphics don't do it justice. I love the movement and cover logic you've given the guys. Really fun to try to flank the enemies.

localcoder says ...

The cover-based gameplay is great and you've made it fun and easy to control. Shopsupgrade systems are always good, and I love trying to surround the enemies and stop them from surrounding my guys.

I found switching between teams with spacebar a bit awkward at first, and would rather be able to press 1 and 2 or some other keys to select the different teams.

HybridMind says ...

I have made Cavern Station safe for my Killbot babies!! :)

I spent $43,700 along the way towards defeating level 5.

Man, nice and strange game. I really liked it. It took a bit to get used to the movement/command controls and the camera controls but at some point I 'got it' and it was really fun to keep quickly outflanking the enemy positions and wiping them out.

Enjoyed the simplistic but elegant graphics and beam weapons as well as the great and simple sound effects. Level 5 battle was sufficiently exciting and tough with the 3 simultaneous enemy tanks!

I'm impressed you managed to get an upgrade system bolted in place that seems fairly balanced too! Nice work man and good luck on making a more in depth sponsor-able version of this!

philomory says ...

This is a pretty impressive result for 48 hours, though it's a little confusing.
