Research and Development mod for Half-Life 2

This mod is brilliance...

I think one of the things you did extremely well which few others seem to be able to pull off is that you had an abundance of relatively difficult puzzles with no spoon feeding, yet at the same time the solutions were logical and apt... there was no moments of drawn out frustration wondering "what the fuck do I do now" but at the same time I never felt like the game was saying "over here idiot"...

Length was excellent... *kind of a spoiler* though I found the end to be a bit abrupt, I guess I was expecting a meet up with the other human/s and face an 'onslaught' of a culmination of the enemies faced, with the help of antlions of course... though the epilogue does kind of allude to something like this so if a sequel is intended then the ending is perfect as it is...

Also, the moderation of gameplay elements was superb... you introduced things (eg breaking pipes) and used them enough for them to be understood a used in a few different ways but never did anything became repetitious or tedious...

Anyways THANK YOU for making an actual FUN GAME, something a lot of people seem to not comprehend...

This is better than episode 1 and on par with episode 2...

10/10

WOW, just ... wow. Guys, this was the most creative, original, and just plain FUN mod that I've played in a long, long time. I absolutely loved it from start to finish. Some of the puzzles even confused me to the point where I'd give up for a night and then come back the next day, having thought about what the heck I was supposed to be doing to get past that part of the level.

Just an amazing piece of work here. Thanks!

A very clever interpretation of HL2. Being very loyal to the play mechanics and feel of HL2, it feels like a worthy extension of the series. This one is puzzle-based, though it still has its moments of intense action - especially on the cart ride!

the level design and art are great, feeling like a continuation of City 17. its lack of actors and occasional release from 1st person view during cinematics are the only departures from the Valve canon, but in no way hurts the quality of the game. Definitely wouldn't mind a sequel. Nice work!

Pros: Very entertaining, beautiful visuals and average level design, challenging and varied puzzles, nice concept.

Cons: Absolutely nothing, I love it. Best 2009 mod by me.

Suggestions: Research And Development 2 with Coop mode, bigger and even more challenging puzzles! And of course, Mr. Whirly should come back even powerful than before =D

Truly truly amazing. That was the best fps singelplayer experience Ive had in a long time, every challenge just felt so rewarding. I would be more then happy if there would be a sequel or a similar game.

Only thing it lacks is a unique soundtrack.

I just completed and all I can say is:
Wow. This was the best mod I've ever played.
Not cheap, not boring.

Ultimate action and epic cutscenes!
Thx for that!

I just stumbled upon this brilliant mod, an exceptional combination of intricate level design and way too clever puzzles, a couple of them which kept me occupied for minutes if not longer. The whole Mr. Whirly level was the icing on the cake, and I loved the short epilogue, which begs for a sequel.

As everyone has stated already... if there's ever a sequel I'd play it in an instant. This is hands down one of the best mods ever for HL2, I haven't seen this level of inventiveness and awesomeness since Minerva.

This is a MUST-download !!!

Praise: Great Mod. Clever design. Loved all puzzles, specialy the lazer (light) puzzle, and the microwave. Did I mention I loved the puzzles?

Trash: Battle with chopper (the 2nd one) unnecessary. nothing else to trash.

Sugestion: implement hint system to help players that are stuck.

Challenge: Make a coop mod with puzzles.

My only problem was that I died two or three times using the vehicle. Would be nice to implement a "garrys mod"-like seat, in which you really "sit" and are, well, welded to the vehicle, so you cant get crushed when you jump and fly into a wall or the strider.

But still 9/10 for it truly is one of the best hl2-mods.

Just finished going through it. Wow. I loved R&D. Please make a sequel! Fantastic job in every respect. If you haven't played this yet, grab it immediately!
