YMMV / Half-Life: Invasion

• Awesome Moments: Time nuking the alien cavern's ceiling right and you'll get two incoming "flybees" caught in the blast and sent to oblivion. Considering the hell these beast give you, it bears an immense Catharsis Factor in addition to sparing you a good portion of your health^and nerves.
• Demonic Spiders: The "flybee" enemy^note redeemed from a cut HL1 npc makes a truly formiddable opponent. It frantically flies around, takes a lot of punishment, its attacks hurt and never miss. Unless you manage to take it out before it has a chance to attack you're dead meat.
  • The "gorgs" double as Goddamned Bats - they're squishy but move incredibly fast, are nigh-impossible to hit due to their small size and have a habit of swarming you and jolting you to death in a matter of seconds.
• Disappointing Last Level: The final part consists of few conjoined underground caverns full of Goddamned Bats and the finale is a nonsensical element-based puzzle followed by a faux-dramatic ending cutscene.
• Goddamned Bats: The "gorg" - a weird small one-eyed limbless frog-like creatures that fly very quickly and deliver nasty jolts. They are about the size of Snarks^note the squeaky bugs from the original game which makes them nigh impossible to hit beyond the range of their bolts and have a habit of swarming you and zapping you to death in the matter of seconds. The only upside to them is that they always fly straight towards you which makes them a bit easier to hit.
• Scrappy Mechanic: Several puzzles are these especially the one with the explosive crates you have to deliver to a trash compactor using a set of reversable conveyor belts. Not only is switching the direction ludicrously tricky and tedious, the GUI has a habit of disappearing and you have to relaunch^note quit to OS and run the application the game to fix that. On top of that the crates are delivered to the conveyor belt in an elevator - which like all HL1 elevators do, has that infamous habit of getting anything inside stuck to it permanently. Considering on how much bad luck do you have the puzzle may end up Unwinnable by Design.
  • Right after it there is that extending bridge timed puzzle. The bridge retracts way too quickly for you to scamper down the ladder in time and hopefully jump to the other side. You can't jump out of the control room windows because the developer put invisible barrier there exactly to prevent it.
