Nice retro Fps with quite an atmosphere to it ^^
I feel like you nailed the low poly retro look, and the various chrome effects with the texture filtering gave the visuals a feel mixed between retro 3Dfx pc game and N64 game in the best possible way.
The atmosphere is really a strong point here, you really conveyed well that apocalyptic feeling of the AI going out of controls right from the first level through the ruins with that Tower in the distance and the giant mechs waiting all around, along with these T-1000 like clones runing around and quite numerous too.
Sadly i had a few issues, first off the game lacks quite a bit of feedback, both when shooting the enemies, and most importantly when taking damage, this issue is especially frustrating when a melee enemy manages to sneak up behind you and your health just melts away, and with the laser accurate hitscan turrets, in the first level there was one kilometers away that killed me really fast before i even understood it was there :/
I also got a bit confused in the last level with these Energy Cores ? Ammo Pickups ? like the one the main character on the artwork is holding but i couldn’t seem to be able to interract with them so i just rushed towards the exit since i wasn’t sure i could actually deal any damage to the giant mech.
Now with that said, despite these issues i’ve really enjoyed playing this one, just needs a bit of polish to fix some things but it already has a lot going for it, good main chara design, interesting setting/premise, cool weapon selection, and nicely done retro visuals.
Good work overall :)
