This is definitely a UE4 project. He discusses the engine in the YouTube description.

Name of engine?

Cellular, old-school, sci-fi, retro-FPS action inspired by Quake II, Battletanx, and even (too a MUCH smaller extent), Osmosis Jones and Army Men: Sarge's Heroes! 7 weapons with each unique function! Secrets galore in virtually every level to collect! Fight through many ranks of the Crimson Viruses and their vehicles, as well as the nasty wildlife in underliquid swimming areas! Listen to awesome heavy metal and synth music from White Bat while you're ramming Viruses with total carnage while driving an auto-chariot!

Now with DirectX 12 Software Raytracing!

Noted. Thank you.

Does this engine support web browser use? HTML5 or WebGL?

I'd love to run my games on the Itch.io website.

Thank you.

Wish this had wedgies to add to the mix.

Yes. It did the trick.

I looked into it, however it seems it bloats in size as I play more Flash games. Fortunately Adobe recently released a projector to rectify the disruption of Flash game support.

Thank you. Playing now.

Its freezing and stuttering.

I shall give this Flash Projector a try.

Adobe Flash discontinued. The game no longer works.

Thanks! Rachet & Clank: Up Your Arsenal was the primary source of inspiration combined with Warhammer 40K's Space Marine drop pods when developing this game.

I have a hunch this may be an Unreal Engine 4 game.

This was fantastic! The music and art style blends perfectly with this game! I truly enjoyed playing with Shadowriver and other players online.

Thanks! It is quite difficult I will admit. I wanted to make the AI more skilled than those jokes from my previous jam entries, but I guess I should have made some of the planes dormant instead. You can accelerate forward then u-turn opposite of your direction and spray bullets the enemy planes intensively. Alternatively, you can target the larger planes and gun them down or more score (while dodging attacks from other enemy planes).

Glad to meet a fellow fan of Army Men and my game.
We're actually planning to re-brand it for a commercial project, and the website expired, but the download is working once more on the page.

If you guys need any help, let me know. I am really impressed with the progress this game has demonstrated.

Do you lot have a Discord page I can join?

Thanks! I might expand on the game concept in the near future.

That and the art style also emits the same vibe.

EDIT: Nvm, It's RPG Maker MV (one of your videos gave it away).

Somehow I get a Fleischer Studios vibe from this game.

What game engine did you use to make this?

Funny you mentioned that.

My game Maze Qore Arena was suppose to sell for $5 and yet zero purchases last week. Most who saw my game claimed it was great, but still refused to buy it. When i finally received some meaningful criticism, I decided to make it PWYW for any better luck, didn't do a damn thing. So I am stumped and screwed it seems. More depression to my self-esteem.

Just trying to find what I am doing wrong so I can get some money and publicity.

UPDATE: I've decided to use the Pay What You Want model for my game. You can download it for free, and if you like it, donate a few dollars and help me push forward the features coming to the game.

Greetings folks! I have recently released my first commercial game on this website at the very low price of $4.99. 

I've spent 2.5 weeks creating this game singlehandedly. The game is currently in early-access and only the singleplayer campaign is available, so I will add multiplayer and user mod support in the near future, as well as a custom level editor for users to create and distribute through the game.

Give it a try and tell me what you all think of it. Any feedback and constructive criticism is welcome.
