That’s exactly what I did, but still wouldn’t work. I’ve used two different unzippers. I’ve even downloaded the file several times. The title screen works but the actual game wont load.

I really enjoyed the mod ,nice touch the little homage to Marioworld collecting the cabbages to get more life energy.

So this is basically how a game is defined “random”. I love it!

I found the snark temple but nothing happens. I also found a key, but it doesn’t open anything
Help, anyone?

never mind.. i found the LITTLE hole i was supposed to put the key in
it really bugs me that i don’t have the target in the center of the screen. other than that, it’s an enjoyable ride (not that hilarious as i thought, though)

kd4tkm, try it without the console. I`ve had the same problem, but works fine when i play it without the console. Good luck!

I’m mesmerized!Great fun, quite weird. I liked the modified HUD with the pointers to show if you can use something. Very deus-exy

A very enjoyable and wacky mod. Had me chuckling throughout. I just wish I could understand Russian; there was the odd moment that I was distracted from reading the subtitles.I love the amount of effort put into this mod. The HUD, the weapon decals, the sounds and music all add to the atmosphere and distinctifies (is that a word?) Ispitel from other HL mods. A pet peeve is playing a mod that relies on its storyline to tell you that’s you’re not Gordon Freeman while the visuals and some voices clearly indicate you are.
Play Ispitatel. Don’t expect to play Half-Life per say. Just accept that this is somewhere in the HL world. Or the world HL could be after taking some recreational narcotics

Hahaha… very well, This is…. a ‘Great’ crazy mod…

This is a good sightseeing mod with lots of strangness however it has almost zero action and so i can;t really recommend it. No replay value, interesting but i’ve seen more action in a point and click adventure game. Only download if you’d like to see a movie rather than play a game.

This mod very strange even for a russian soul. And it forms very strange opinion and feelings too.
THE LIGHT SIDE: Impressive parody humor like nothing; unlimited imagination of authors that broken all standarts of other mods; incredible quality of voice recording; good custom textures, sounds, models; minimum bugs.
THE DARK SIDE: Feeling of no-control (for sample, episode at bridge with bricks, my character tell me what I must to doo + invisible wall, and final scene, there’s not working second variant of choice); noclips on a way when isn’t need; one type of enemy at all time; stupid missions like “find that and put it here”. I have felt strange emptiness and senselessness upon the end of game.
My vote 3 of 5.

Oh, sorry, I said “noclips”, it means “player clips”, haha.

Most of you liked it?
Sorry, I didn’t like Ispitatel1,2,3 at all. Nr 4 is a lot better, I played it once but won’t play it any longer. Find it just too stupid.
A huge map, I expected a lot of it but – comparing it with other huge maps – I find it of a lower class…
Vind het gewoon te stom om dood te doen, graphics trekken op niks, als je al aan wapens raakt, ‘verdwijnen’ ze steevast als je in een nieuw level raakt. Houterige figuurtjes, enfin… prul. (mijn mening)

This is quite a good mod, nice story, but i seem to have seen some unused models like v_laserrifle(s), or others, i think the author planed a other storys, but got canceled, i think i just put a Maybe on it.
