Story

The HL Invasion story starts at the end of Half-Life. Remember, you were in a train with the strange G-man … Fortunately, scientists hidden in a subsidiary laboratory with Black Mesa manage to repatriate you there with a space probe, in which you jumped just before the G-man kills you.

Once awoken, you discover this secret laboratory that the government forces haven’t discovered yet. You are watching a teleportation experience, when suddenly over-trained marines invade this hiding place … From this moment, you’ll never be alone … This new trip will lead you into subsidiary areas with Black Mesa where you’ll get more revelations about the government objectives and the world of Xen …

    Actually, just had a thought. It’s not something to do with the transparency dll files, is it?

    key codes do not work. used the numeric keypad with numlock on or off. tried with “use key” on and with “S” on ; no help. also how do I reduce the size of the man; he occupies 25% of the screen. this mod is good but buggy.

    Personal Favourite

    WOW, this was my very first mod for any HL game i played!!!, how was i going to forget!!, is like a flashbulb memory, about me, trying to experiment with the files where i had no idea of how to run a mod propperly, arround 2004-05 or so!!

    So is my personal Fav. because is special really is, it was the first and i just loved it!!, new weapons, new crazy story from those french developers!! man i love this mod!, i was freaked out when i use the sniper riffle!!, and that Tank drivable ride!!! wow, i discover why mods are called mods!!! LOL i tought HL1 only have the same boring weapons untill i discover this jewel.

    Is a great classic mod that i really loved, you have to play it, if you are an experimented mod gamer then this mod would be maybe kind of lower to you, but for me being the very first mod i played, was a BLAST!! i could even say this is the reason of why i’m adicted to HL mods, definietely close to my heart, that really outweights the rest of the tech arguments about this mod for me.

    Game is HARD to play, for me borderline of having to reload so many times that i didn’t want to play the game because it’s not fun to re load so often. I enjoy the story & not how challenging it is to beat the game i.e. i don’t play all the difficulties.

    Pros
    detachable limbs when killed

    variety of weapons

    blue suit; how you can apply energy to specific parts

    Different ways of getting killed i.e. the cylinders down the stairs then exploding.

    CONS:
    Same items are destructible & non destructible w/ no indicator if what’s non destructible; wasted precious ammo!!

    Digital pads are a nice visual, but not necessary

    fag lighter; the lighter has more fuel than the flashlight has power (?_?)

    firearms sound & look more powerful than what i’m used to; M16 fires like a M60!

    Enemy tank that can see thru everything and keep you in the cross-hairs (¬_¬)

    Tank section of the game where you drive…except for blowing up soldiers w/ satisfaction w/ main gun, everything about it was a disaster!

    Gargantua that you can’t kill, but dies from a giant fan @@

    NO Hollywood ending ب_ب

    During the tank driving section i had enough; i cheated. You can cheat by typing “testmode” in the console → then sv_cheats 1 → then your cheats of preference. If you save a game or it crashes and you need to reload your game w/ cheats, you will have
    1. start a new game or load a game w/ no cheats saved on them
    2. Load your game w/ the cheats codes activated.

    Great mod that adds a lot of new features to the original gameplay. It has it own unique style and the maps look absolutely lovely. Invasion has many new enemies and weapons. Some are a hit and others are a miss. Very classic HL puzzle and action pacing. The thing that stands out about this mod is that the mod maker put so much effort in minor details that you may miss on your first playthrough.

    There were some gameplay elements I didn’t care for, like making health packs and batteries as inventoried items. But it didn’t detract from the gameplay much. The enemies seem to have incredible aim, but they go down easier. The only thing I really hated was the lack of a flashlight, the lighter was absolutely useless. Invasion is a bit buggier then your average HL1 mod.
