Research and Development is a puzzle-centric mod for Half-Life 2: Episode Two featuring an unarmed player but plenty of violent mayhem.
A truly fantastic mod.
The puzzles are diverse and interesting.
Some parts are frustrating (Cart riding with grenade throwing enemies, and the start of Chapter 4), but the rest is a real blast... literally.
There's also some funny momments and a few references (e.g. A-Team).
The only reason it's not getting a 10, is that it took me 3 hours to complete, which is too short. Others might get more time out of it, so I imagine it deserving a higher score for those cases.
Overall, it's a must play, and i cannot wait to see a sequel to it!
The start was amazing, I really really enjoyed it and the cart ride thingo was the most fun I'd got out of Source for a while. However, the boss fights were tedious, the vehicle section was glitchy (I wasted about half an hour thanks to one particular bug) and the Strider fight was just plain frustrating.
A good game from an amazing team that I (mostly) thouroughly enjoyed, it's just a shame the end let it down.
I've almost finished playing, so might as well review.
I loved this mod, it was very clever. Some things were a bit frustrating, but then, I'd just do something else, come back to the mod later and solve it. My only real issue is the fact I've spotted quite a few bugs in a single playthrough. (For instance, there's a point where I saw a Combine soldier just standing in mid-air as if he had used noclip, and later on I had the weirdest bug with the buggy.(pun not intended))
All in all, great mod, but there's a few bugs I've seen, one of which is game-breaking and thus needs fixing in my opinion.
