WARNING: This strat seems to be very hardware-dependant. Sorry if it doesn't work for you <3

Regrettably, this game really likes to crash on Mission 2: City Dump. Luckily it seems this can mostly be avoided. The level seems perfectly stable up until the robot spider fight. I'll walk you through the whole thing.

The spider is scripted to walk to a specific spot. While walking there it cannot take damage, so save your ammo. When it clears a distinct-looking pile of rubble it will start to turn to face you. This indicates that the fight has started.

Avoid physical contact with the spider at all times. Fire a grenade directly below the spider while making sure to avoid the spider's legs (can be an instant crash).

After firing, look away immediately. If the spider is in your field of view during the explosion the game may crash. A single well-placed explosive should be enough to kill the spider. When "dead", it will move to another predetermined spot where it will explode, and the nearby destructible wall will collapse.

So that's the whole fight. Walk to position, fight until health drops to 0, when "dead" walk to position, explode. If your first grenade didn't do the trick fire some more, just keep those same rules in mind. If you're unsure whether the fight is over or not, when the spider "dies" it drops a Shield pickup in the form of a toolbox. If you see this, the spider is "dead" and walking to the predetermined position where it can explode and let you proceed.
