Machine Party Lethal Rebound

Overview

Lethal Rebound fills an arena with hacksaws, bounce panels, and narrow ledges where players shove rivals into spinning blades. Physics rebounds can eliminate multiple test subjects in one chain — exactly the spectacle Oro Interactive highlights in Steam’s mature content description. The Steam achievement Will it blend? tracks 15 people pushed into hacksaws (cumulative) across your account, not a single round miracle.

Global unlock sat near 0.3% in early August 2026, tying Will it blend? with Full Pack from Smoking Contest as the rarest badges in Machine Party — plan multiple hunt sessions with the same friends.

Rules

Lethal Rebound rewards spacing reads and angle control. Shove toward hacksaw arcs, not open floor — rebounds off panels can redirect victims into secondary blades. Trailers show multi-kill chains when bodies pile near machinery.

Personal survival still matters for gene mutation points even while grinding cumulative shoves — see scoring and mutations. Do not confuse environmental hacksaw deaths with shove-attributed kills — Steam likely credits player-initiated pushes. Confirm with one test shove and achievement progress tick before marathon nights.

Physics arenas hitch when frame rates drop — chains fail to register. Use --rendering-driver d3d12 if black screens appear between rounds; see troubleshooting and Steam Deck and Linux.

Tactics

Fifteen cumulative hacksaw shoves spread across many Lethal Rebound rounds. Host custom lobbies and repeat the mode; full fixed-order playlists only visit Lethal Rebound once per hour-long marathon.

Farmer and feeder roles work best: one player shoves, another positions victims near hacksaw arcs. Study rebound panel angles in slow custom rounds before marathon grinds — shove victims into panel centers, not glancing edges, when hunting reliable hacksaw entries. Spend one unscored round mapping each panel’s bounce angle; shallow redirects waste shove animations without crediting Will it blend? progress.

Track progress in Steam achievement details if exposed — otherwise count manually until the pop-up fires. A shove that looks correct locally may redirect victims away from blades on high ping — prefer wired connections from multiplayer. Compare chaos and difficulty tiers: Lethal Rebound ranks high on both, so expect swingy outcomes even when technique is solid.

Lethal Rebound sits in reflex challenges with Debris Platforms and Stable Footing. Displacement kills define all three, but only Lethal Rebound ties to cumulative hacksaw shoves. Warm up spacing reads in Duck Hunt between rebound nights.

Party size notes

Four-player Lethal Rebound generates more shove targets per round for Will it blend? cumulative hunting. Duos lengthen the grind but reduce mis-attributed environmental kills. Feeder and farmer roles rotate each round — see party sizes when planning marathon nights.

Achievement hunt

Will it blend? requires 15 people pushed into hacksaws (cumulative) — not one round, not environmental kills alone. Schedule joint hunt nights with Smoking Contest for Full Pack — both sit at ~0.3% and require repeat custom lobbies. Alternate modes each hour to reduce physics fatigue.

Gene mutation standings from scoring and mutations still reward survival rounds even while farming shoves — do not ignore session placement entirely during marathon nights. Attempt Minefield Leg it! runs when fresh, not after Lethal Rebound chaos — spatial memory suffers when blade-chain adrenaline lingers.
