Source review — 10 November 2026: This is an original-game loadout from the dated guide below. Accessible source pages confirm the listed weapon attachment names. Perks and equipment retain their original dated attribution; the source review does not imply hands-on testing or a fresh balance-patch analysis.
The HK21 is a free LMG from level 2, with gamer.org's July 2026 list calling it good at sustained fire but noting its recoil, and rating it B-tier. Double its magazine. This applies to the original 2010 game as hXc Hector documents it.
Best HK21 loadout
No major guide publishes a build for this gun, so this is our suggested setup from its available attachments. hXc Hector alone lists per-gun attachments (page timestamp 14 July 2022), with Video Games Blogger's 18 November 2010 guide confirming the LMG set as a class.
| Slot | Pick | What it does |
|---|---|---|
| Attachment | Extended Mag | Called the Drum Mag on this gun; 60 rounds per magazine instead of 30, no extra total ammo |
| Tier 1 perk | Lightweight | Move 7% faster, helping a class that moves at 87.5% speed |
Why this build works
A 30-round magazine is small for a machine gun, and hXc's other figures reward sustained fire: an estimated 40 damage per bullet at 750 RPM, with no range drop-off listed. Drum Mag fits the role gamer.org describes. Its reload, at 3.1-4.5 seconds, is the reason not to be caught short. The HK21 has no Grip on his list, so the recoil has to be managed by hand. Lightweight offsets the class's slow movement, which hXc pegs at the lowest speed in the game alongside launchers.
How to play it
hXc recommends LMGs at medium to long range, and says they have lower accuracy than assault rifles. Fire in bursts at distance, as he advises for automatics. LMGs have high penetration on his page, so shooting through thin cover is worth trying.
Unlock notes
Available at level 2 with no purchase price listed. The Extended Mag costs C1000. Lightweight is unlocked by default, per hXc Hector.
