I called out sliding as one of my favourite aspects of Arc Raiders in a launch-day write-up. It lends the looter shooter a gambolling giddiness you might not expect from its heavily laden packmule characters. In more practical terms, it makes you harder to hit and allows you to flank or retreat while regenerating stamina, the catch being that you might slide into somewhere you'd rather not be, like directly beneath a bunch of Hornets.
After a few hours spent doing migrant penguin impressions in Buried City and Blue Gate, a thought occurred: hang on, this is almost like the hypermobile ski shooting in Tribes: Ascend. I mean, not really, but perhaps if they made friction a setting on custom servers, this crouch-walking pillage 'em up could be a bona fide movement shooter.
