28 comments by Varsity on Jul 20th, 2009

PC gaming super-blog Rock, Paper, Shotgun loves R&D! In a new review Alec Meer praises the mod as "a seismic shift" away from the norm, telling readers that it is "as must-play as an HL2 mod gets":

R&D’s hook is that it’s essentially non-combative. Yep – you go without guns throughout (bar the ol’ Gravity jobbie, but hey, that’s more about construction than destruction here). Sure, you can tell an Antlion to claw someone to death or arrange to squash men with falling girders, but you’re definitely not Edward Pistolhands. It’s an environmental adventure game, taking the irregular physics and logic puzzles seen in HL2 itself and turning them into the game itself. Mazes, gravity, exploding microwaves and fire-retardant antlion carapaces all make an appearance – it’s very much a point’n’click adventure in an FPS engine.

If you still haven't played Research and Development, which requires Episode Two, download it now!

Update: Destructoid also has a very positive review.

After the part where I have to corral the 3 antlion (queens?) I crash while crawling into the warehouse. :(

As far as I played though it's ******* impressive as ****.

Setting the few bugs aside, you've made a hell of a game, pal. 9/10 for this release and 10/10 if the bugs get fixed.

Because the mod profile was made after the mod was finalised, this mod wasn't shown to the public untill the release.

Let me start by saying this was exactly what I was looking for when I began looking through the hl2 mods available here. For some reason I love any puzzle elements executed in the hl2 engine and enjoyed all the little puzzles you had to solve throughout the actual hl2 game itself and R&D pretty much mixes all those great moments into one sweet package.

Research & Development pretty much a perfect mod for any fps puzzle lovers and the only thing I can hope for now is a sequel :D
