    I beta tested this map some years ago, and there is no plot of story as such, it was meant has an opening map for a mod that never got started let a lone finished, I think the author calls himself AJ, is it very much a what you see is what you get. It’s very short without any balance of play, just short sharp combats within tight interior situations. Don’t recommend a download plenty of finished game out there to get on with.

    OK, When will it be part 2? I liked it.
    It was one of the Lambda Core recreations. I even heard grunts. You said “to be continued…” and you MUST make part 2 ASAP!
    All I can say is…

    A well designed level placed in a classic Black Mesa like. No story but good action. Shame that this mod don’t have a sequel.

  5. Maybe?

    After refusing Gman’s offer and returning from Xen via teleporter which brought him to the Lambda Core again, Freeman does not know what’s to expect there now…

    It’s only a pity that this mod seems to be never finished, as there is a lot of potential imo.
    It has the typical BM feeling and the maps are decent, altho undetailed and empty.
    According to the readme it’s “demo / partial”, so don’t expect too much. As for a demo it’s okay, but it just lacks too many things to make it more interesting.
    There are also some bugs which are surprising on the one hand, and annoying on the other hand.

    However, it was fun to play. But it’s not recommendable for playing it more than once.

    -Decent mapping with average lighting
    -BM feeling
    -Some nice combat situations
    -A few puzzles
    -A few, but not important scripts

    -Undetailed, empty maps – makes you think there’s something missing at all times
    -No story
    -Short playtime (~15-30 mins)
    -Bugs like exit door does open after “using” it three times, altho a button is required (so you can finish the mod a few minutes earlier than it was meant to be!), also minor graphic bugs
    -Besides BM is looking like BM, there’s not much atmosphere
    -Minor design oddities

  6. Ten Four Reviews

    As the name implies, Return to Lambda Core takes us back into Black Mesa. However, it thankfully doesn’t take us back to overdone themes; no, this time we’re revisiting one of the more unique chapters of the Half-Life singleplayer game.

    As expected, texturing is in the Lambda Core style with a healthy infusion of themes from HL’s Intro and Office Complex. The visual re-creation of the Core is quite convincing, including a re-cast of the original’s side-area exploration which will reward in weapons and ammo. There is, however, one glaring clipping/construction bug, but this fortunately does not detract from the gameplay experience in any way whatsoever.

    Plenty of combat is guaranteed, with an array of alien grunts, alien slaves, headcrabs, and zombies (and one icthyosaur), including some Marines. However, the presence of the Marines not only offsets the cramped level design (they’re suited to more open areas a la Surface Tension or We’ve Got Hostiles), but they’ve been overused as well, making certain fights extremely difficult. Fewer Marines would have been benefitted the level design more, as would have a surplus of puzzles and/or set-pieces (which are sorely lacking).

    Return to Lambda Core does have its flaws, but as this is a first-time release, they can be easily overlooked. What is here is a solid, enjoyable experience in the Lambda Core tradition that delivers a good amount of action. Just don’t go in expecting too much…certainly don’t think that this has all the annoyances of Lambda Core either. This is a fine release indeed; the continuation that the author has promised will undoubtedly be one to watch.

  7. Maybe?

    Lambda Core is a small map pack that is very faithful to some of the sections seen in Half-Life’s chapter of the same name. The design is pretty spot on. However there are some issues. It’s interesting seeing HECU grunts in here alongside the Xen aliens, though a lot of the combat spaces feel a little too tight to fully take advantage of them. The shotgunners however? They are absolutely lethal here.

    Some scaling issues also appear throughout the map pack, with computer terminals and keyboards appearing really high off the ground.

    There are also no living friendly NPCs, which means there are no entertaining sequences that play out, nor are there any snippets of plot or narrative so you’re largely running blind. I presume that in a full release, the objective would be to get out of Black Mesa, but sadly it appears this short release is the only form of this map pack that was released.

    With some more polish and a more complete pack, this might have become one of the classics. The fact that it did not is a real shame.
